1
00:00:02,172 --> 00:00:03,797
NARRATOR: Sunken continents
said to have once been home

2
00:00:03,880 --> 00:00:06,713
to advanced civilizations.

3
00:00:06,797 --> 00:00:08,838
An ancient shipwreck

4
00:00:08,922 --> 00:00:12,380
containing what might be
evidence of Atlantis.

5
00:00:12,463 --> 00:00:16,672
And unidentified
submersible objects

6
00:00:16,755 --> 00:00:19,005
moving through our oceans.

7
00:00:19,130 --> 00:00:21,422
For more than a decade,
Ancient Aliens

8
00:00:21,505 --> 00:00:24,047
has traveled the globe
to investigate

9
00:00:24,130 --> 00:00:26,213
some of the most
puzzling discoveries

10
00:00:26,297 --> 00:00:28,505
made in the depths
of our oceans.

11
00:00:28,588 --> 00:00:30,463
Now we're exploring

12
00:00:30,547 --> 00:00:33,213
the top ten
mysteries of the deep

13
00:00:33,297 --> 00:00:34,672
that just may hold the proof

14
00:00:34,755 --> 00:00:39,422
that Earth has been visited
by extraterrestrials.

15
00:00:46,297 --> 00:00:50,380
The ocean is the most
mysterious place on Earth.

16
00:00:50,463 --> 00:00:53,422
It covers 70% of our planet,

17
00:00:53,547 --> 00:00:57,172
but less than 10% of it
has been explored.

18
00:00:57,213 --> 00:01:00,338
In fact, we know more
about the surface of Mars

19
00:01:00,463 --> 00:01:04,172
than we do about
the bottom of our own oceans.

20
00:01:04,297 --> 00:01:06,880
But what we have
discovered in the depths

21
00:01:06,880 --> 00:01:09,297
is a treasure trove of evidence

22
00:01:09,380 --> 00:01:11,630
for the ancient
astronaut theory.

23
00:01:11,630 --> 00:01:14,422
Like an incredible
underwater formation

24
00:01:14,547 --> 00:01:18,422
that was found off the coast
of Japan in the 1980s.

25
00:01:19,422 --> 00:01:21,338
Number ten on our countdown

26
00:01:21,463 --> 00:01:23,963
of the top ten mysteries
of the deep:

27
00:01:24,047 --> 00:01:26,297
The Yonaguni Monument.

28
00:01:28,213 --> 00:01:29,672
NARRATOR:
In the Pacific Ocean,

29
00:01:29,755 --> 00:01:33,130
at the westernmost tip
of the Japanese archipelago,

30
00:01:33,213 --> 00:01:37,005
lies the small
island of Yonaguni.

31
00:01:37,088 --> 00:01:41,047
In 1987, in nearby waters,

32
00:01:41,130 --> 00:01:44,255
dive tour operator
Kihachiro Aratake

33
00:01:44,380 --> 00:01:46,797
made a shocking discovery.

34
00:01:46,880 --> 00:01:50,755
He found a massive complex
of stone formations

35
00:01:50,755 --> 00:01:55,172
that lay hidden a mere 60 feet
beneath the ocean's surface.

36
00:01:56,380 --> 00:01:59,297
ROBERT SCHOCH:
It's an absolutely
incredible structure.

37
00:01:59,380 --> 00:02:02,255
It looks like a giant staircase.

38
00:02:02,338 --> 00:02:06,838
There are steps
in the bedrock with terraces.

39
00:02:08,213 --> 00:02:12,047
The symmetry and the regularity
that people see on it

40
00:02:12,172 --> 00:02:14,047
just makes
a astounding impression.

41
00:02:15,172 --> 00:02:20,213
HUGH NEWMAN:
It looks like a huge,
multifaceted pyramid platform

42
00:02:20,297 --> 00:02:22,255
that stretches over a huge area

43
00:02:22,338 --> 00:02:24,588
with all these details
carved into it.

44
00:02:24,672 --> 00:02:29,130
There's areas where monoliths
were said to have been standing.

45
00:02:29,213 --> 00:02:33,338
There's even dolmens,
or large slabs like lintels

46
00:02:33,422 --> 00:02:38,255
covering areas and creating
doorways and other features.

47
00:02:38,338 --> 00:02:41,380
NARRATOR:
Although some
researchers suggest

48
00:02:41,463 --> 00:02:43,463
that the so-called
Yonaguni Monument

49
00:02:43,547 --> 00:02:45,588
is simply a rock formation,

50
00:02:45,672 --> 00:02:49,338
many experts, including
Japanese archeologist

51
00:02:49,422 --> 00:02:52,297
Masaaki Kimura,
have come to believe

52
00:02:52,380 --> 00:02:54,255
it is an artificial structure

53
00:02:54,338 --> 00:02:57,213
that was built
in the distant past.

54
00:02:57,297 --> 00:02:58,547
(speaking Japanese)

55
00:02:58,630 --> 00:03:00,255
TRANSLATOR: There are
several reasons why

56
00:03:00,380 --> 00:03:02,797
I think this is not
a natural formation.

57
00:03:05,213 --> 00:03:08,130
A number of tools and
numerous engraved stones

58
00:03:08,213 --> 00:03:10,297
were found at the site.

59
00:03:10,380 --> 00:03:13,880
Because of these things,
there is no doubt to me

60
00:03:13,963 --> 00:03:16,297
that this was made artificially.

61
00:03:18,880 --> 00:03:21,838
TSOUKALOS:
There are all these different
cuts that seem to be

62
00:03:21,922 --> 00:03:26,255
of artificial origin
and not of a natural origin...

63
00:03:27,213 --> 00:03:31,172
...because it's too precise.

64
00:03:32,547 --> 00:03:37,130
Was Yonaguni artificially
altered at a time

65
00:03:37,213 --> 00:03:40,547
when the water levels
of the oceans were lower?

66
00:03:41,630 --> 00:03:43,922
We know that this happened
at some point

67
00:03:43,922 --> 00:03:47,672
during the last ice age,
which was 14,000 years ago.

68
00:03:49,255 --> 00:03:51,797
NARRATOR:
Could this massive
underwater structure

69
00:03:51,797 --> 00:03:55,838
really be the remnants
of an advanced civilization

70
00:03:55,963 --> 00:03:59,880
that existed here on Earth
more than 10,000 years ago?

71
00:04:01,130 --> 00:04:03,713
And if so, who built it?

72
00:04:03,797 --> 00:04:06,505
ROB SIMONE:
The Yonaguni Monument is
particularly interesting

73
00:04:06,505 --> 00:04:08,422
because some of
the reports suggest that

74
00:04:08,422 --> 00:04:10,505
this was built 20,000 years ago.

75
00:04:10,547 --> 00:04:13,213
So the question is
how was it built

76
00:04:13,297 --> 00:04:15,588
with this limited ability
of these people

77
00:04:15,713 --> 00:04:18,255
that were known to have
exist in that time?

78
00:04:18,338 --> 00:04:21,213
If they had
extraterrestrial help,

79
00:04:21,338 --> 00:04:24,713
it would solve a lot of problems

80
00:04:24,797 --> 00:04:27,547
in trying to understand
how a civilization

81
00:04:27,672 --> 00:04:31,838
could mount
such a daunting enterprise

82
00:04:31,880 --> 00:04:36,005
without what we see are
the necessary skills to do so.

83
00:04:36,130 --> 00:04:40,172
NARRATOR:
Was Yonaguni built
thousands of years ago

84
00:04:40,255 --> 00:04:44,005
with the help of
extraterrestrial beings?

85
00:04:44,088 --> 00:04:46,338
Perhaps clues about
its construction

86
00:04:46,463 --> 00:04:50,630
can be found in the mythology
of Japan's royal family.

87
00:04:50,713 --> 00:04:53,088
It was said in ancient Japan,

88
00:04:53,172 --> 00:04:57,380
that the dragon god lived
at the bottom of the ocean.

89
00:04:57,463 --> 00:05:00,005
His daughter had a daughter,

90
00:05:00,047 --> 00:05:03,880
and her child was Jimmu,
the first emperor of Japan.

91
00:05:05,172 --> 00:05:07,338
To be descended from a dragon

92
00:05:07,380 --> 00:05:11,880
is to be from the divine
dimension of nature,

93
00:05:11,963 --> 00:05:14,630
but also from the stars.

94
00:05:17,047 --> 00:05:22,255
DAVID CHILDRESS:
When these underwater structures
of Yonaguni were found,

95
00:05:22,380 --> 00:05:25,838
the Japanese became thrilled.

96
00:05:25,922 --> 00:05:30,713
They believed that evidence
for extraterrestrials

97
00:05:30,797 --> 00:05:33,547
was right there
in southern Japan.

98
00:05:37,505 --> 00:05:42,088
To me, the Yonaguni Monument
presents clear evidence

99
00:05:42,172 --> 00:05:45,380
that an advanced society
existed on Earth

100
00:05:45,505 --> 00:05:48,672
long before our earliest
recorded history.

101
00:05:48,755 --> 00:05:51,588
And, in fact,
numerous ancient cultures

102
00:05:51,672 --> 00:05:55,922
around the world tell similar
stories of lost civilizations,

103
00:05:56,005 --> 00:06:00,338
including one that ended up
submerged beneath the sea.

104
00:06:00,463 --> 00:06:02,630
Number nine on our countdown

105
00:06:02,713 --> 00:06:05,297
of the top ten
mysteries of the deep:

106
00:06:05,380 --> 00:06:08,338
The Lost Continent of Mu.

107
00:06:09,505 --> 00:06:11,672
NARRATOR:
The Pacific Ocean.

108
00:06:11,713 --> 00:06:15,255
This body of water
is the largest on Earth,

109
00:06:15,338 --> 00:06:19,047
covering more than
63 million square miles.

110
00:06:19,130 --> 00:06:21,463
Curiously, many ancient peoples

111
00:06:21,547 --> 00:06:23,422
living throughout
this vast expanse

112
00:06:23,547 --> 00:06:25,338
share the same story

113
00:06:25,422 --> 00:06:28,463
of a long-lost
sunken civilization

114
00:06:28,547 --> 00:06:32,338
often referred
to as Lemuria, or Mu.

115
00:06:33,422 --> 00:06:36,172
Mu was this huge continent

116
00:06:36,213 --> 00:06:38,630
that supposedly existed

117
00:06:38,713 --> 00:06:40,963
from Hawaii in the north,

118
00:06:41,047 --> 00:06:44,505
down to Easter Island
in the southeast,

119
00:06:44,588 --> 00:06:48,380
right the way across
to Micronesia in the west.

120
00:06:48,463 --> 00:06:52,088
It thrived perhaps
50,000 years ago,

121
00:06:52,213 --> 00:06:55,338
and was sunk beneath the waves,

122
00:06:55,422 --> 00:06:59,588
possibly at the end
of the last ice age.

123
00:06:59,672 --> 00:07:03,130
NARRATOR:
Among the many legends
expressed by Polynesians

124
00:07:03,213 --> 00:07:04,672
and native Hawaiians,

125
00:07:04,713 --> 00:07:07,338
one is that
the lost continent of Mu

126
00:07:07,380 --> 00:07:10,797
was home to visitors
from the Pleiades.

127
00:07:11,838 --> 00:07:13,797
We have all kind of
connection with the Pleiades,

128
00:07:13,880 --> 00:07:15,255
but we call it,
uh, ka po'e o ka lani,

129
00:07:15,338 --> 00:07:16,172
"the people of the heaven."

130
00:07:31,463 --> 00:07:34,005
WILLIAM HENRY:
The Hawaiians believed
that the Hawaiian Islands

131
00:07:34,088 --> 00:07:37,172
were originally part of Mu,

132
00:07:37,297 --> 00:07:38,380
and the belief
is that the Pleiadeans

133
00:07:38,463 --> 00:07:39,963
were the original
settlers of Mu.

134
00:07:41,338 --> 00:07:43,130
NARRATOR:
While most mainstream scholars

135
00:07:43,213 --> 00:07:45,380
dismiss the stories of Mu

136
00:07:45,380 --> 00:07:47,755
as being little more
than a fanciful myth,

137
00:07:47,838 --> 00:07:52,255
ancient astronaut theorists
claim that remnants of Mu

138
00:07:52,338 --> 00:07:53,713
can still be found today

139
00:07:53,797 --> 00:07:56,963
in the mysterious
ruins of Nan Madol.

140
00:07:59,172 --> 00:08:02,630
Nan Madol is a huge basalt city

141
00:08:02,713 --> 00:08:04,672
that sits on the edge

142
00:08:04,713 --> 00:08:06,338
of the island of Pohnpei

143
00:08:06,422 --> 00:08:09,797
in Micronesia
in the Pacific Ocean.

144
00:08:09,880 --> 00:08:12,838
It's made up of
hundreds of thousands,

145
00:08:12,963 --> 00:08:16,922
potentially millions,
of these huge basalt columns,

146
00:08:17,005 --> 00:08:18,588
and much of the site

147
00:08:18,672 --> 00:08:20,338
is still submerged in the water,

148
00:08:20,422 --> 00:08:22,172
suggesting it must
have been built

149
00:08:22,213 --> 00:08:24,047
many thousands of years ago.

150
00:08:25,213 --> 00:08:28,547
SCHOCH:
Some people actually suggested
that maybe Nan Madol

151
00:08:28,630 --> 00:08:31,172
was the last remnant of Mu

152
00:08:31,255 --> 00:08:32,797
that was still above water,

153
00:08:32,880 --> 00:08:35,713
and it was simply indicative

154
00:08:35,797 --> 00:08:38,880
of what had sunk
beneath the waves

155
00:08:38,963 --> 00:08:42,005
from this advanced civilization.

156
00:08:43,047 --> 00:08:46,172
NARRATOR:
Could it be that
the structures on Nan Madol

157
00:08:46,297 --> 00:08:50,047
are ruins of an ancient
extraterrestrial civilization

158
00:08:50,130 --> 00:08:52,255
known as Mu?

159
00:08:52,338 --> 00:08:54,630
According to Rufino Mauricio,

160
00:08:54,713 --> 00:08:57,838
the Director of the Federal
States of Micronesia

161
00:08:57,922 --> 00:09:02,630
Office of National Archives,
it's a distinct possibility.

162
00:09:31,255 --> 00:09:35,088
Legends of lost civilizations
and sunken cities

163
00:09:35,213 --> 00:09:38,422
can be found in cultures
all around the world.

164
00:09:38,505 --> 00:09:41,422
But one has captured
the public's imagination

165
00:09:41,505 --> 00:09:43,047
more than any other.

166
00:09:43,130 --> 00:09:45,672
And some believe
we may have found

167
00:09:45,755 --> 00:09:49,588
evidence of its existence
in the Bermuda Triangle.

168
00:09:49,672 --> 00:09:53,088
Number eight on our top ten
mysteries of the deep:

169
00:09:53,172 --> 00:09:54,547
Atlantis.

170
00:09:56,880 --> 00:09:59,172
NARRATOR:
For over 2,000 years,

171
00:09:59,255 --> 00:10:01,797
the lost continent of Atlantis

172
00:10:01,880 --> 00:10:06,672
has sparked the imaginations
of historians and explorers.

173
00:10:06,755 --> 00:10:08,922
The first reference
of Atlantis that we have

174
00:10:08,922 --> 00:10:13,797
is in Plato's dialogues
by Timaeus and Critias.

175
00:10:14,755 --> 00:10:16,922
In the very end of Timaeus,
it talks about

176
00:10:17,005 --> 00:10:19,297
this mythical place
called Atlantis

177
00:10:19,380 --> 00:10:23,797
from where any and all
knowledge of the world came.

178
00:10:24,797 --> 00:10:27,130
And so, some people
have suggested

179
00:10:27,213 --> 00:10:31,797
that the first civilization on
Earth may have been Atlantean.

180
00:10:33,338 --> 00:10:34,838
CHILDRESS:
According to legend,

181
00:10:34,922 --> 00:10:38,880
Atlantis was founded
by the god Poseidon.

182
00:10:39,963 --> 00:10:44,338
He fell in love with
a human woman named Cleito,

183
00:10:44,422 --> 00:10:48,213
and they had five sets of twins.

184
00:10:48,297 --> 00:10:52,922
And these twins went on
to be the founders of Atlantis.

185
00:10:53,838 --> 00:10:55,088
YOUNG:
Atlantis is thought to be

186
00:10:55,172 --> 00:10:58,297
a great civilization
of high culture

187
00:10:58,380 --> 00:11:00,672
and technological achievement.

188
00:11:01,713 --> 00:11:04,380
They had robotics at
a very advanced level.

189
00:11:04,463 --> 00:11:06,672
The power of levitation,
which is how

190
00:11:06,713 --> 00:11:08,422
they built
their glorious cities.

191
00:11:08,505 --> 00:11:10,422
They had achieved things

192
00:11:10,505 --> 00:11:12,797
that we still
are not able to do.

193
00:11:14,047 --> 00:11:15,630
NARRATOR:
According to Plato,

194
00:11:15,713 --> 00:11:18,422
Atlantis was destroyed
in a single night

195
00:11:18,505 --> 00:11:19,922
by a cataclysmic flood,

196
00:11:20,005 --> 00:11:23,255
which some identify
as the Great Flood

197
00:11:23,338 --> 00:11:25,172
described in the Bible.

198
00:11:25,297 --> 00:11:29,963
But where the famous city
was located remains a mystery.

199
00:11:30,047 --> 00:11:34,422
Atlantis was allegedly
this land mass that existed

200
00:11:34,547 --> 00:11:37,588
beyond the Pillars of Hercules,

201
00:11:37,713 --> 00:11:39,797
which is today's
Strait of Gibraltar,

202
00:11:39,797 --> 00:11:42,880
and to this day,
if Atlantis existed,

203
00:11:42,963 --> 00:11:45,922
we have no idea
where exactly Atlantis was.

204
00:11:46,963 --> 00:11:48,838
NARRATOR:
While most mainstream historians

205
00:11:48,922 --> 00:11:51,213
dismiss the story
of the sunken civilization

206
00:11:51,297 --> 00:11:53,172
of Atlantis as a myth,

207
00:11:53,255 --> 00:11:56,838
ancient astronaut theorists
believe it really existed.

208
00:11:56,880 --> 00:12:00,005
And as evidence, they point
to a remarkable discovery

209
00:12:00,130 --> 00:12:02,713
made off the coast of Cuba.

210
00:12:08,130 --> 00:12:11,838
Canadian explorer
Paulina Zelitsky and her team

211
00:12:11,922 --> 00:12:15,172
are conducting an oceanic
survey off the coast

212
00:12:15,297 --> 00:12:17,505
when they detect
curious formations

213
00:12:17,588 --> 00:12:20,672
more than 2,000 feet underwater.

214
00:12:20,797 --> 00:12:23,755
PAULINA ZELITSKY:
I was in control room
on board of the ship.

215
00:12:23,838 --> 00:12:27,130
There suddenly appeared

216
00:12:27,213 --> 00:12:30,755
a very large, very dark images

217
00:12:30,838 --> 00:12:34,005
of, uh, perfect
geographical shapes.

218
00:12:47,505 --> 00:12:50,505
NEWMAN:
They found, when
they were taking images,

219
00:12:50,588 --> 00:12:52,630
some kind of
pyramidical structure

220
00:12:52,713 --> 00:12:55,005
and other structures.

221
00:12:55,047 --> 00:12:56,797
There were circular areas,

222
00:12:56,880 --> 00:12:58,213
there was what appeared to be

223
00:12:58,297 --> 00:13:00,130
some kind of city
built down there.

224
00:13:00,213 --> 00:13:04,005
It was about two square
kilometers in size.

225
00:13:04,047 --> 00:13:06,172
And so, this is something
quite astonishing

226
00:13:06,255 --> 00:13:08,630
if this is, you know, a reality.

227
00:13:08,713 --> 00:13:10,547
COLLINS:
And almost certainly,

228
00:13:10,672 --> 00:13:13,422
this dates back
several thousand years,

229
00:13:13,547 --> 00:13:15,547
and arguably even earlier,

230
00:13:15,630 --> 00:13:18,422
and is part of
a lost civilization.

231
00:13:19,505 --> 00:13:22,005
NARRATOR:
Is it possible
that the underwater ruins

232
00:13:22,088 --> 00:13:27,088
off the coast of Cuba are
the actual remains of Atlantis?

233
00:13:27,172 --> 00:13:30,422
Ancient astronaut
theorists say yes,

234
00:13:30,505 --> 00:13:32,505
and as further evidence,

235
00:13:32,588 --> 00:13:36,088
they point to their location
near the Bermuda Triangle,

236
00:13:36,172 --> 00:13:39,797
a region notorious
for mysterious lights,

237
00:13:39,880 --> 00:13:41,797
strange disappearances

238
00:13:41,880 --> 00:13:44,505
and unexplained phenomena.

239
00:13:45,547 --> 00:13:48,547
CHILDRESS:
It's speculated
that in Atlantis,

240
00:13:48,630 --> 00:13:52,547
they were creating huge pyramids
and energy devices.

241
00:13:52,547 --> 00:13:56,380
The idea is that there is
still one of these pyramids,

242
00:13:56,463 --> 00:13:59,797
and it's active beneath
the Bermuda Triangle

243
00:13:59,922 --> 00:14:01,213
on the ocean floor,

244
00:14:01,297 --> 00:14:04,338
and it's creating
these anomalies

245
00:14:04,463 --> 00:14:07,713
that are sometimes seen there
at the Bermuda Triangle.

246
00:14:07,797 --> 00:14:10,297
If you are a researcher
into Atlantis,

247
00:14:10,380 --> 00:14:13,838
this is exactly
the kind of discovery

248
00:14:13,880 --> 00:14:16,297
that you are looking for.

249
00:14:16,380 --> 00:14:20,588
Some kind of pyramid
that's underwater.

250
00:14:20,672 --> 00:14:22,797
And in fact, this may well be,

251
00:14:22,880 --> 00:14:25,380
really, the evidence
for Atlantis that we need.

252
00:14:26,588 --> 00:14:29,838
Did Atlantis really exist?

253
00:14:29,922 --> 00:14:32,713
Recently, a mysterious
metal alloy was recovered

254
00:14:32,797 --> 00:14:34,672
from the depths of the ocean

255
00:14:34,672 --> 00:14:36,422
that may offer further evidence.

256
00:14:37,088 --> 00:14:39,755
Number seven on our countdown:

257
00:14:39,838 --> 00:14:41,422
Orichalcum.

258
00:14:45,630 --> 00:14:48,963
NARRATOR:
Sicily. 2015.

259
00:14:50,838 --> 00:14:53,463
Archaeologist Sebastiano Tusa

260
00:14:53,547 --> 00:14:57,088
excavates a shipwreck
less than a mile off the coast,

261
00:14:57,172 --> 00:15:01,213
which has remained undisturbed
for more than 2,600 years.

262
00:15:01,338 --> 00:15:03,672
His team dredges up
an ancient payload

263
00:15:03,755 --> 00:15:06,505
of 39 metal ingots.

264
00:15:06,547 --> 00:15:10,463
Spectrographic analysis
of the recovered alloy

265
00:15:10,547 --> 00:15:14,005
reveals the compound
is unlike anything

266
00:15:14,088 --> 00:15:15,672
ever found in the ancient

267
00:15:15,713 --> 00:15:18,047
or modern world.

268
00:15:19,838 --> 00:15:21,547
The interesting part about this

269
00:15:21,672 --> 00:15:24,338
is the composition
of the ingots that they found.

270
00:15:25,380 --> 00:15:29,922
The metal is 80% copper,
and 20% zinc.

271
00:15:30,005 --> 00:15:31,838
There was other things
found in it,

272
00:15:31,922 --> 00:15:34,797
but that's the majority
of the composition.

273
00:15:34,880 --> 00:15:36,838
What's interesting about this

274
00:15:36,922 --> 00:15:39,547
is that zinc doesn't
naturally occur.

275
00:15:39,630 --> 00:15:41,963
We didn't have zinc until
about a thousand years ago,

276
00:15:41,963 --> 00:15:43,838
and this is 2,600 years old.

277
00:15:43,838 --> 00:15:48,172
NARRATOR:
How is it possible
that such an advanced alloy

278
00:15:48,255 --> 00:15:50,505
was produced
thousands of years ago,

279
00:15:50,588 --> 00:15:54,797
centuries before man had
the technology to create it?

280
00:15:54,880 --> 00:15:57,505
After conducting an analysis,

281
00:15:57,505 --> 00:15:59,963
scientists believe
the mysterious alloy

282
00:16:00,047 --> 00:16:03,297
is orichalcum,
a metal associated

283
00:16:03,380 --> 00:16:06,380
with the legendary
continent of Atlantis.

284
00:16:07,838 --> 00:16:09,130
CHILDRESS:
According to Plato,

285
00:16:09,213 --> 00:16:14,963
orichalcum was
an orangish gold-type metal

286
00:16:15,047 --> 00:16:17,172
that was used in Atlantis.

287
00:16:17,255 --> 00:16:19,005
It's thought that orichalcum

288
00:16:19,047 --> 00:16:23,047
was some kind of
alloy of copper and gold,

289
00:16:23,172 --> 00:16:26,297
and the walls of Atlantis
were wallpapered,

290
00:16:26,422 --> 00:16:29,797
literally,
with this reddish-gold metal.

291
00:16:29,880 --> 00:16:31,672
NARRATOR:
According to Plato,

292
00:16:31,755 --> 00:16:34,713
this metal was given
to the people of Atlantis

293
00:16:34,797 --> 00:16:37,338
by the Greek god Cadmus.

294
00:16:38,547 --> 00:16:40,838
JASON MARTELL:
The actual discovery
of the orichalcum metal

295
00:16:40,922 --> 00:16:43,005
lends credence
to the idea that Cadmus

296
00:16:43,130 --> 00:16:44,880
did exist at one time,

297
00:16:44,963 --> 00:16:46,547
passing this knowledge
to humanity.

298
00:16:46,672 --> 00:16:50,338
And Atlantis could be
an actual physical location,

299
00:16:50,380 --> 00:16:53,838
possibly harnessing and
utilizing other advanced metals.

300
00:16:54,880 --> 00:16:57,922
The reason why this ties in to
the ancient astronaut theory

301
00:16:58,005 --> 00:17:00,088
is based on an idea

302
00:17:00,172 --> 00:17:02,255
that the ancient gods of Greece

303
00:17:02,338 --> 00:17:05,797
were visiting extraterrestrials.

304
00:17:05,880 --> 00:17:08,380
NARRATOR:
Could this mysterious metal,

305
00:17:08,463 --> 00:17:10,797
found deep beneath
the ocean's surface,

306
00:17:10,880 --> 00:17:13,672
be proof that humans
lived side by side

307
00:17:13,755 --> 00:17:17,422
with otherworldly beings
thousands of years ago?

308
00:17:17,505 --> 00:17:20,005
Ancient astronaut
theorists say yes,

309
00:17:20,172 --> 00:17:22,797
and suggest that
further evidence

310
00:17:22,880 --> 00:17:26,838
of extraterrestrial contact
can be found submerged

311
00:17:26,880 --> 00:17:30,255
in the waters
off the coast of India.

312
00:17:40,088 --> 00:17:42,880
India is a treasure trove

313
00:17:42,963 --> 00:17:44,588
for the ancient
astronaut theory.

314
00:17:44,713 --> 00:17:49,047
Its mythology is chock-full
of stories of flying chariots

315
00:17:49,172 --> 00:17:52,713
and god-like beings
descending from the sky.

316
00:17:52,797 --> 00:17:56,422
And every so often,
the ocean offers us evidence

317
00:17:56,547 --> 00:17:58,963
that these stories
could be true.

318
00:17:59,047 --> 00:18:01,338
At number six on our list

319
00:18:01,422 --> 00:18:04,172

320
00:18:04,255 --> 00:18:07,463
The Lost Pagodas
of Mahabalipuram.

321
00:18:09,880 --> 00:18:11,713
NARRATOR:
Mahabalipuram, India.

322
00:18:11,797 --> 00:18:15,672
On December 26, 2004,

323
00:18:15,713 --> 00:18:17,505
a powerful tsunami

324
00:18:17,588 --> 00:18:20,547
caused the water levels
in the city's harbor to drop.

325
00:18:20,672 --> 00:18:23,255
As the waters receded,

326
00:18:23,338 --> 00:18:25,880
residents noticed
something astonishing

327
00:18:25,963 --> 00:18:27,338
emerging from the sea:

328
00:18:27,380 --> 00:18:30,755
the ruins of several
ancient buildings.

329
00:18:32,213 --> 00:18:35,922
SCHOCH:
The ocean receded
about 500 or so meters,

330
00:18:36,005 --> 00:18:38,338
and people that were there,

331
00:18:38,422 --> 00:18:42,588
they said they saw walls,
they saw structures

332
00:18:42,672 --> 00:18:45,505
that they'd never seen before
'cause now the water was gone.

333
00:18:46,880 --> 00:18:48,922
NARRATOR:
For the more than
one billion Hindus

334
00:18:49,005 --> 00:18:50,213
around the world,

335
00:18:50,297 --> 00:18:52,630
the discovery of
these underwater ruins

336
00:18:52,713 --> 00:18:56,172
was remarkable because
they may provide evidence

337
00:18:56,213 --> 00:18:58,380
that a sensational story

338
00:18:58,380 --> 00:19:01,588
contained in ancient sacred
texts called the Puranas

339
00:19:01,672 --> 00:19:04,547
is not mythological
but historical.

340
00:19:05,713 --> 00:19:09,255
According to the story,
thousands of years ago,

341
00:19:09,338 --> 00:19:12,505
seven pagodas stood
at Mahabalipuram,

342
00:19:12,588 --> 00:19:15,588
but six of them became
submerged beneath the sea

343
00:19:15,672 --> 00:19:18,213
after the city
was attacked by a god

344
00:19:18,338 --> 00:19:21,005
who came down from the sky.

345
00:19:21,047 --> 00:19:23,255
CHILDRESS:
The legend at Mahabalipuram

346
00:19:23,338 --> 00:19:25,797
says that the god Indra
became jealous

347
00:19:25,880 --> 00:19:30,172
of the special treatment of the
other gods depicted at the site.

348
00:19:30,213 --> 00:19:33,755
And that he then sent
a flood against the city.

349
00:19:35,213 --> 00:19:37,713
Hindu mythology
really reads like

350
00:19:37,838 --> 00:19:40,380
the wildest
science fiction of today.

351
00:19:41,380 --> 00:19:44,672
It's filled with
all kinds of magic stones,

352
00:19:44,755 --> 00:19:47,963
flying spaceships.

353
00:19:48,047 --> 00:19:50,505
TSOUKALOS:
In fact, ancient India,

354
00:19:50,630 --> 00:19:54,338
their entire pantheon
of gods is based

355
00:19:54,422 --> 00:19:58,213
exclusively on a cosmic origin,

356
00:19:58,297 --> 00:20:01,422
that they arrived
from deep space.

357
00:20:02,755 --> 00:20:05,380
NARRATOR:
For centuries,
many Hindus believed

358
00:20:05,463 --> 00:20:07,880
that the Shore Temple
at Mahabalipuram

359
00:20:08,005 --> 00:20:12,297
represented the one surviving
pagoda from Indra's attack.

360
00:20:12,380 --> 00:20:14,672
Could the structures
that were revealed

361
00:20:14,755 --> 00:20:17,838
by the receding
ocean levels in 2004

362
00:20:17,922 --> 00:20:21,130
be the remnants
of the other six pagodas,

363
00:20:21,213 --> 00:20:24,047
proving that
the incredible story is true?

364
00:20:24,130 --> 00:20:29,005
CHILDRESS:
At Mahabalipuram, you have
evidence that the legends

365
00:20:29,130 --> 00:20:32,005
are really correct
about this place.

366
00:20:32,047 --> 00:20:36,005
That it's far more ancient
than archeologists assumed.

367
00:20:36,088 --> 00:20:38,213
And it would seem
to be an indication

368
00:20:38,297 --> 00:20:41,172
that this was a real event,

369
00:20:41,255 --> 00:20:44,422
one that perhaps
included extraterrestrials.

370
00:20:45,380 --> 00:20:47,213
If you leave Mahabalipuram

371
00:20:47,297 --> 00:20:50,255
and travel
1,000 miles northwest,

372
00:20:50,338 --> 00:20:52,297
you will find
another mysterious site

373
00:20:52,380 --> 00:20:54,422
off the coast of India.

374
00:20:54,505 --> 00:20:58,130
20 feet beneath the waves
are the ruins of an ancient city

375
00:20:58,213 --> 00:21:01,963
that some believe was the home
of an extraterrestrial being.

376
00:21:02,047 --> 00:21:04,963
Number five on our list:

377
00:21:05,047 --> 00:21:06,922
The Sunken City of Dwarka.

378
00:21:10,463 --> 00:21:12,797
NARRATOR:
Dwarka, northwest India.

379
00:21:12,880 --> 00:21:15,588
April 1983.

380
00:21:16,672 --> 00:21:19,880
Marine archeologist Dr. S.R. Rao

381
00:21:19,880 --> 00:21:22,755
begins a seven-year
underwater exploration

382
00:21:22,838 --> 00:21:25,505
just off the coast
of this ancient fishing town,

383
00:21:25,588 --> 00:21:28,838
and what he finds is stunning.

384
00:21:28,922 --> 00:21:32,713
Submerged 20 feet beneath
the surface of the ocean,

385
00:21:32,797 --> 00:21:36,880
he finds sandstone walls,
cobblestone streets,

386
00:21:37,047 --> 00:21:40,422
and further evidence
of a prosperous ancient city

387
00:21:40,505 --> 00:21:42,963
that sank into the sea.

388
00:21:44,547 --> 00:21:48,380
At Dwarka, what has been
found so far under the ocean

389
00:21:48,463 --> 00:21:50,380
is incredibly tantalizing.

390
00:21:51,547 --> 00:21:53,672
For instance,
there's this huge wall,

391
00:21:53,755 --> 00:21:56,880
estimated about 580 meters long.

392
00:21:57,005 --> 00:22:00,880
Pottery has been found,
anchors have been found,

393
00:22:00,880 --> 00:22:02,963
so this seems to have been
a maritime city.

394
00:22:04,713 --> 00:22:07,630
COLLINS:
The remains that have been
discovered beneath the waters

395
00:22:07,713 --> 00:22:10,505
have been radiocarbon dated

396
00:22:10,547 --> 00:22:14,588
to at least 9,500 years.

397
00:22:15,672 --> 00:22:18,338
So, this was
many thousands of years

398
00:22:18,463 --> 00:22:21,672
older than that of Sumeria,

399
00:22:21,755 --> 00:22:23,755
Egypt and China.

400
00:22:25,588 --> 00:22:27,422
So, what exactly was going on

401
00:22:27,505 --> 00:22:29,213
in India at this time?

402
00:22:29,297 --> 00:22:31,088
NARRATOR:
For centuries,

403
00:22:31,172 --> 00:22:33,130
the modern-day city of Dwarka

404
00:22:33,213 --> 00:22:34,838
was thought by many Hindus

405
00:22:34,880 --> 00:22:37,922
to be the Dwarka
described in the Mahabharata

406
00:22:37,922 --> 00:22:41,922
as the ancient kingdom
of the god Krishna.

407
00:22:43,005 --> 00:22:46,338
According to the text,
during the Kurukshetra war,

408
00:22:46,422 --> 00:22:48,963
a rival to Krishna,
Lord Salva,

409
00:22:49,047 --> 00:22:52,422
attacked Dwarka
from a flying chariot.

410
00:22:54,297 --> 00:22:58,172
He actually,
uh, flew over Dwarka,

411
00:22:58,255 --> 00:22:59,672
using his chariot,

412
00:22:59,797 --> 00:23:03,422
and he started bombarding
the city of Dwarka,

413
00:23:03,505 --> 00:23:06,130
throwing down
all kinds of weapons.

414
00:23:07,505 --> 00:23:11,005
Shortly after the great war,
Krishna is killed.

415
00:23:12,005 --> 00:23:14,672
And the city,
this magnificent city

416
00:23:14,713 --> 00:23:17,505
built on land that
came out of the sea,

417
00:23:17,630 --> 00:23:21,672
sank back into the ocean again.

418
00:23:21,713 --> 00:23:25,505
It only existed during the time
that Krishna lived there.

419
00:23:29,713 --> 00:23:31,672
COLLINS:
Is it possible

420
00:23:31,755 --> 00:23:35,380
that the pre-Vedic
cultures of India

421
00:23:35,463 --> 00:23:37,338
really did have high technology?

422
00:23:37,463 --> 00:23:39,547
And I think, from
the ancient accounts

423
00:23:39,630 --> 00:23:42,338
and what's now been
discovered at Dwarka,

424
00:23:42,422 --> 00:23:44,505
the answer has to be yes.

425
00:23:48,297 --> 00:23:51,005
The discoveries at
Dwarka and Mahabalipuram

426
00:23:51,088 --> 00:23:54,880
provide sensational evidence
that ancient Hindu stories

427
00:23:55,005 --> 00:23:58,963
of advanced technology
are not works of fiction.

428
00:23:59,047 --> 00:24:02,588
And there is yet another
incredible underwater structure

429
00:24:02,713 --> 00:24:05,172
located between
India and Sri Lanka

430
00:24:05,297 --> 00:24:07,172
that may offer further proof.

431
00:24:07,297 --> 00:24:09,088
Number four on our list:

432
00:24:09,172 --> 00:24:10,838
Rama's Bridge.

433
00:24:13,172 --> 00:24:17,672
NARRATOR:
Just off the southeastern
tip of India lies Sri Lanka.

434
00:24:17,713 --> 00:24:20,547
This island nation has been
an important trading hub

435
00:24:20,630 --> 00:24:22,338
for thousands of years,

436
00:24:22,463 --> 00:24:24,797
but it is nearly impossible

437
00:24:24,880 --> 00:24:27,672
for ships to pass between
Sri Lanka and India

438
00:24:27,755 --> 00:24:31,338
due to a more than 30-mile-long
underwater barrier

439
00:24:31,422 --> 00:24:33,672
that links the two landmasses.

440
00:24:34,713 --> 00:24:37,797
TSOUKALOS:
If you look at satellite
imagery, you can see

441
00:24:37,880 --> 00:24:42,672
that there seems to be some
sort of a connector, a road.

442
00:24:42,755 --> 00:24:47,213
This is referred to
as Rama's Bridge.

443
00:24:47,297 --> 00:24:50,005
NARRATOR:
The mainstream viewpoint
is that Rama's Bridge

444
00:24:50,088 --> 00:24:52,797
is a chain of natural
limestone shoals.

445
00:24:52,880 --> 00:24:56,213
But millions of Hindus
believe the barrier is,

446
00:24:56,297 --> 00:24:58,713
in fact, an ancient bridge,

447
00:24:58,713 --> 00:25:01,255
one that was built by the god
for whom it is named.

448
00:25:02,547 --> 00:25:04,922
Rama is a major Hindu deity,

449
00:25:05,047 --> 00:25:08,588
considered by some
to be the supreme being.

450
00:25:08,588 --> 00:25:12,672
According to the ancient
Sanskrit text the Ramayana,

451
00:25:12,755 --> 00:25:16,505
Rama's wife was kidnapped and
taken to the kingdom of Lanka.

452
00:25:17,672 --> 00:25:21,672
To rescue her, Rama used
magical construction techniques

453
00:25:21,755 --> 00:25:24,463
to build a bridge to Lanka.

454
00:25:24,547 --> 00:25:28,047
Some of the interesting details
of the building of Rama's Bridge

455
00:25:28,130 --> 00:25:31,755
is that they were writing
Rama's name on these stones

456
00:25:31,838 --> 00:25:35,005
and that would magically
levitate the stones.

457
00:25:35,047 --> 00:25:37,088
And some of these
were very big stones, too.

458
00:25:38,547 --> 00:25:40,005
SHIMKHADA:
According to the mythology,

459
00:25:40,047 --> 00:25:44,255
you know, Rama lived
around 6,000 years ago,

460
00:25:44,380 --> 00:25:47,838
and there is interesting fact
that some geologists

461
00:25:47,922 --> 00:25:52,172
carbon-date the material
on the bottom

462
00:25:52,213 --> 00:25:54,547
approximately dating
around the same time.

463
00:25:54,547 --> 00:25:57,005
So that kind of corroborates
whether or not

464
00:25:57,130 --> 00:26:01,172
this story is connected
to the mythology

465
00:26:01,213 --> 00:26:05,047
because the age of Rama
is around that period.

466
00:26:05,130 --> 00:26:09,838
NARRATOR:
In 2018, government
officials in India

467
00:26:09,922 --> 00:26:12,338
voted against plans
to cut a shipping lane

468
00:26:12,422 --> 00:26:13,880
through the middle
of the barrier,

469
00:26:14,005 --> 00:26:16,255
showing their support
for the notion

470
00:26:16,380 --> 00:26:19,630
that the underwater structure
known as Rama's Bridge

471
00:26:19,713 --> 00:26:22,755
was, in fact,
built by the Hindu deity.

472
00:26:24,213 --> 00:26:27,797
CHILDRESS:
Rama's Bridge
to Sri Lanka is real.

473
00:26:27,880 --> 00:26:30,338
And you have to ask
yourself, was it built

474
00:26:30,422 --> 00:26:34,838
artificially by levitating
stones and putting them there?

475
00:26:34,963 --> 00:26:36,963
That's what
the Ramayana tells us.

476
00:26:49,005 --> 00:26:51,755
Some of the mysteries
we've investigated

477
00:26:51,838 --> 00:26:54,547
on Ancient Aliens
are so baffling,

478
00:26:54,672 --> 00:26:58,005
we can only guess at
what might explain them.

479
00:26:58,047 --> 00:27:00,755
And perhaps one of
the most mystifying

480
00:27:00,880 --> 00:27:03,338
lies on the islands of Malta.

481
00:27:03,463 --> 00:27:05,797
Number three on our countdown

482
00:27:05,880 --> 00:27:08,338
of the top ten
mysteries of the deep:

483
00:27:08,422 --> 00:27:10,172
The Malta Cart Ruts.

484
00:27:14,172 --> 00:27:16,672
NARRATOR:
In the middle of
the Mediterranean Sea,

485
00:27:16,755 --> 00:27:21,213
just south of Sicily,
lies the Republic of Malta.

486
00:27:22,755 --> 00:27:24,380
This tiny island nation

487
00:27:24,463 --> 00:27:27,297
boasts some of the most
impressive megalithic structures

488
00:27:27,380 --> 00:27:28,547
on the planet.

489
00:27:28,630 --> 00:27:30,922
And crisscrossing the islands

490
00:27:31,005 --> 00:27:33,380
is something even
more mysterious:

491
00:27:33,463 --> 00:27:37,547
a complex network of grooves
carved into the bedrock

492
00:27:37,630 --> 00:27:41,005
known simply as the "cart ruts."

493
00:27:42,005 --> 00:27:43,297
SCHOCH:
Something that Malta

494
00:27:43,380 --> 00:27:45,838
is very well known for
archaeologically,

495
00:27:45,922 --> 00:27:49,172
besides the megalithic temples,

496
00:27:49,255 --> 00:27:50,380
are the cart ruts.

497
00:27:51,755 --> 00:27:56,255
These are ruts literally
in the limestone rock.

498
00:28:11,838 --> 00:28:13,297
TSOUKALOS:
If you have grooves

499
00:28:13,380 --> 00:28:17,463
that were created by some sort
of a transportation device,

500
00:28:17,547 --> 00:28:20,338
well, it had to have been
pulled by something,

501
00:28:20,380 --> 00:28:23,963
so where are the footprints?

502
00:28:24,047 --> 00:28:27,338
There are no footprints.

503
00:28:29,172 --> 00:28:32,963
NARRATOR:
How and why the cart ruts
were formed remains a mystery,

504
00:28:33,047 --> 00:28:37,213
but their existence
poses a profound possibility,

505
00:28:37,297 --> 00:28:39,380
because some believe

506
00:28:39,505 --> 00:28:42,713
they may reveal that there
was human activity on Malta

507
00:28:42,838 --> 00:28:45,172
many thousands of years before

508
00:28:45,255 --> 00:28:48,422
what has been suggested
by mainstream archaeology.

509
00:28:50,213 --> 00:28:52,130
TSOUKALOS:
We have cart ruts

510
00:28:52,213 --> 00:28:55,838
that go into
the Mediterranean Sea.

511
00:28:55,922 --> 00:28:58,380
And then they also
come out on the other side.

512
00:28:59,713 --> 00:29:01,505
How is this possible?

513
00:29:05,338 --> 00:29:08,088
NARRATOR:
Some of the cart ruts
that extend from dry land

514
00:29:08,172 --> 00:29:10,963
down into the sea
have reportedly been found

515
00:29:11,047 --> 00:29:14,297
at depths
of as much as 140 feet.

516
00:29:15,505 --> 00:29:17,338
This presents a critical clue

517
00:29:17,422 --> 00:29:20,630
as to just how long ago
they must have been created.

518
00:29:21,672 --> 00:29:25,422
I suspect that some of these
cart ruts are really ancient,

519
00:29:25,505 --> 00:29:27,297
and when I say "really ancient,"

520
00:29:27,380 --> 00:29:29,380
that is going back

521
00:29:29,463 --> 00:29:32,922
to before the end
of the last ice age.

522
00:29:34,088 --> 00:29:38,505
So, approximately,
uh, 12,000 years or so,

523
00:29:38,588 --> 00:29:40,338
the ice age ended, we know.

524
00:29:42,047 --> 00:29:45,588
Some of these cart ruts
going into the water,

525
00:29:45,672 --> 00:29:50,338
that would've been dry land
when sea levels were much lower.

526
00:29:51,838 --> 00:29:54,922
If you propose the idea
that 12,000 years ago,

527
00:29:55,005 --> 00:29:59,172
which is a fact, the worldwide
water levels were lower,

528
00:29:59,297 --> 00:30:01,463
then all of a sudden,
these cart ruts

529
00:30:01,547 --> 00:30:04,338
that go into the Mediterranean
Sea make sense.

530
00:30:05,380 --> 00:30:08,005
The fact that
these cart ruts exist,

531
00:30:08,130 --> 00:30:12,838
to me, illustrates that
an advanced civilization

532
00:30:12,963 --> 00:30:15,297
must have existed at that time.

533
00:30:16,380 --> 00:30:20,005
NARRATOR:
If the cart ruts are
more than 12,000 years old,

534
00:30:20,047 --> 00:30:22,172
as some researchers suggest,

535
00:30:22,213 --> 00:30:24,380
who would have been
around to create them?

536
00:30:25,838 --> 00:30:28,338
It's a question
that continues to baffle

537
00:30:28,463 --> 00:30:30,088
mainstream archaeologists.

538
00:30:30,172 --> 00:30:33,172
But according
to local traditions,

539
00:30:33,213 --> 00:30:35,880
the megalithic
structures on Malta

540
00:30:35,963 --> 00:30:37,838
were built by
a race of giant beings

541
00:30:37,922 --> 00:30:40,547
who came to Earth
from the stars.

542
00:30:42,088 --> 00:30:43,880
HENRY:
We have to be open
to the possibility

543
00:30:43,963 --> 00:30:45,713
that whoever built these

544
00:30:45,797 --> 00:30:47,755
were not, in fact, human beings,

545
00:30:47,838 --> 00:30:49,380
but were perhaps
a separate race,

546
00:30:49,505 --> 00:30:51,838
and their existence
and even their origins,

547
00:30:51,963 --> 00:30:54,088
is completely
shrouded in mystery.

548
00:30:55,380 --> 00:30:57,630
NARRATOR:
Are the so-called "cart ruts,"

549
00:30:57,713 --> 00:30:59,338
that not only crisscross Malta

550
00:30:59,380 --> 00:31:02,380
but extend deep into
the Mediterranean Sea,

551
00:31:02,505 --> 00:31:06,088
evidence of advanced,
otherworldly visitors?

552
00:31:07,172 --> 00:31:09,005
For ancient astronaut theorists,

553
00:31:09,130 --> 00:31:12,213
the answer is a resounding yes.

554
00:31:13,380 --> 00:31:16,755
And they suggest
that the waters of our oceans

555
00:31:16,755 --> 00:31:18,172
not only contain evidence

556
00:31:18,255 --> 00:31:22,005
of extraterrestrial visitation
in the distant past,

557
00:31:22,088 --> 00:31:24,880
but they are the location
of encounters

558
00:31:24,963 --> 00:31:28,922
that are happening
to this very day.

559
00:31:38,088 --> 00:31:43,213
Most people assume that UFOs
are only seen up in the sky.

560
00:31:43,297 --> 00:31:46,088
But what if I told you
that some of the most

561
00:31:46,172 --> 00:31:49,880
widely reported sightings
involve mysterious craft

562
00:31:49,963 --> 00:31:53,130
flying in and out of our oceans?

563
00:31:53,213 --> 00:31:55,172
Number two on our countdown

564
00:31:55,255 --> 00:31:57,838
of the top ten mysteries
of the deep:

565
00:31:57,880 --> 00:32:00,713
Unidentified
Submersible Objects.

566
00:32:06,963 --> 00:32:09,505
NARRATOR:
Hitachi Province, Japan.

567
00:32:09,630 --> 00:32:11,213
1803.

568
00:32:13,463 --> 00:32:17,797
Local fishermen are astonished
when a mysterious metal craft

569
00:32:17,880 --> 00:32:22,088
washes ashore that is unlike
anything they have ever seen.

570
00:32:24,255 --> 00:32:26,172
NICK POPE:
This craft was likened

571
00:32:26,297 --> 00:32:29,380
to the shape of
a Japanese incense burner.

572
00:32:29,505 --> 00:32:34,088
It is almost literally
a flying disk, a flying saucer.

573
00:32:34,172 --> 00:32:36,880
On the outside of this craft

574
00:32:37,005 --> 00:32:40,922
were multiple
small metal plates,

575
00:32:41,005 --> 00:32:44,297
not too dissimilar
to heat-resistant tiles

576
00:32:44,380 --> 00:32:47,005
that you'd find, say,
on a space shuttle.

577
00:32:49,380 --> 00:32:51,380
NICK REDFERN:
A hatch opened,

578
00:32:51,505 --> 00:32:54,130
and a young woman
came out of the craft

579
00:32:54,213 --> 00:32:58,130
dressed in clothes that
had never been seen before,

580
00:32:58,213 --> 00:33:00,088
and speaking a language

581
00:33:00,213 --> 00:33:02,547
that nobody understood
in the slightest.

582
00:33:03,963 --> 00:33:06,005
POPE:
The story of the strange craft

583
00:33:06,088 --> 00:33:10,005
appears in three
different Japanese texts.

584
00:33:10,130 --> 00:33:12,505
Even today, modern historians

585
00:33:12,547 --> 00:33:16,172
struggle to understand
what this means.

586
00:33:17,213 --> 00:33:19,172
NARRATOR:
Another famous incident

587
00:33:19,255 --> 00:33:22,880
involving a strange craft
emerging from underwater

588
00:33:22,880 --> 00:33:25,005
occurred in
Yunnan Province, China,

589
00:33:25,088 --> 00:33:28,338
on October 24, 1991.

590
00:33:28,422 --> 00:33:31,963
A local man was fishing
on Fuxian Lake

591
00:33:32,047 --> 00:33:34,255
on a clear and tranquil day

592
00:33:34,380 --> 00:33:37,338
when a large disc suddenly
flew out of the water.

593
00:33:37,380 --> 00:33:40,047
POPE:
This strange craft

594
00:33:40,130 --> 00:33:43,838
actually emerged from
the waters of the lake.

595
00:33:43,963 --> 00:33:46,463
He described it
as a shining disc.

596
00:33:47,547 --> 00:33:50,963
This UFO was so close
and so powerful

597
00:33:51,047 --> 00:33:53,547
that it actually
tossed the boat around.

598
00:33:54,963 --> 00:33:56,880
And then, rapidly, this craft

599
00:33:56,963 --> 00:33:59,422
just disappeared
up into the sky.

600
00:34:06,672 --> 00:34:10,005
NARRATOR:
Navy personnel
aboard the USS Omaha

601
00:34:10,088 --> 00:34:13,672
capture footage
of a mysterious round object

602
00:34:13,797 --> 00:34:15,672
flying into the ocean.

603
00:34:15,713 --> 00:34:17,338
TAYLOR:
Night footage

604
00:34:17,380 --> 00:34:19,297
actually shows a craft

605
00:34:19,380 --> 00:34:21,630
that is spherical and
it's flying through the air...

606
00:34:23,047 --> 00:34:25,380
...and then suddenly
it flies into the water

607
00:34:25,463 --> 00:34:27,213
without making a splash.

608
00:34:28,713 --> 00:34:31,338
NARRATOR:
Japan. China.

609
00:34:31,463 --> 00:34:32,797
San Diego.

610
00:34:32,880 --> 00:34:36,213
These are just three
out of hundreds of reports

611
00:34:36,297 --> 00:34:38,422
of what are known as "USOs."

612
00:34:38,547 --> 00:34:43,630
BILL BIRNES:
A USO is an "unidentified
submerged object."

613
00:34:44,797 --> 00:34:46,422
It's the same thing as a UFO,

614
00:34:46,505 --> 00:34:48,172
except this one's in the water,

615
00:34:48,297 --> 00:34:49,672
and a UFO is a flying object.

616
00:34:51,088 --> 00:34:53,088
You see them off
the coast of California,

617
00:34:53,213 --> 00:34:55,422
you see them a lot
in the Gulf of Mexico.

618
00:34:55,505 --> 00:34:59,380
Spend some time on
the Florida Gulf Coast,

619
00:34:59,380 --> 00:35:01,380
you will see a USO.

620
00:35:02,547 --> 00:35:04,297
TAYLOR:
These objects are flying along,

621
00:35:04,380 --> 00:35:06,047
uh, through the atmosphere,

622
00:35:06,130 --> 00:35:08,380
and then suddenly,
they go into the ocean.

623
00:35:08,463 --> 00:35:10,963
No splash, no wake, nothing.

624
00:35:11,047 --> 00:35:12,547
They just go
right into the water

625
00:35:12,672 --> 00:35:15,547
and then come out of the water
in many cases, and fly away.

626
00:35:15,630 --> 00:35:17,630
Now, one such never
came out of the water,

627
00:35:17,713 --> 00:35:20,588
and a submarine was actually
dispatched to look for a craft

628
00:35:20,672 --> 00:35:22,797
that may have crashed,
but never found anything.

629
00:35:24,047 --> 00:35:25,547
KAKU:
The stresses and strains

630
00:35:25,630 --> 00:35:27,588
by flying through
the atmosphere,

631
00:35:27,713 --> 00:35:30,630
in outer space and then
plunging into the oceans

632
00:35:30,713 --> 00:35:34,255
would be enough to rupture
any of our known aircraft.

633
00:35:35,297 --> 00:35:37,047
NARRATOR:
For ancient astronaut theorists,

634
00:35:37,172 --> 00:35:38,672
perhaps the most
compelling story

635
00:35:38,797 --> 00:35:41,463
of an extraterrestrial
presence in Earth's oceans

636
00:35:41,547 --> 00:35:43,797
can be found in an account

637
00:35:43,880 --> 00:35:46,338
from 1492,

638
00:35:46,422 --> 00:35:49,172
recorded by
Christopher Columbus.

639
00:35:50,672 --> 00:35:53,505
There's a famous story
about Christopher Columbus

640
00:35:53,630 --> 00:35:55,422
and he wrote this
in his journals...

641
00:35:56,713 --> 00:36:00,338
...that as he was moving
west across the Atlantic,

642
00:36:00,422 --> 00:36:02,838
towards the Caribbean,
in his first voyage,

643
00:36:02,922 --> 00:36:06,963
he saw a light out
in the ocean to the west,

644
00:36:07,047 --> 00:36:09,505
hovering over the water.

645
00:36:09,588 --> 00:36:14,297
And this light then
descended into the water.

646
00:36:14,380 --> 00:36:18,588
So, he's perhaps one of
the first witnesses to describe

647
00:36:18,672 --> 00:36:20,672
a trans-medium craft like this,

648
00:36:20,797 --> 00:36:23,672
which could hover,
uh, above the water

649
00:36:23,797 --> 00:36:25,838
and then disappear
into it like a submarine.

650
00:36:27,797 --> 00:36:32,505
BIRNES:
Stories of undersea objects,
glowing objects

651
00:36:32,588 --> 00:36:34,505
that fly out of the water,
have been around

652
00:36:34,588 --> 00:36:37,172
for well over
thousands of years.

653
00:36:37,213 --> 00:36:41,338
Are these machines
that the extraterrestrials

654
00:36:41,463 --> 00:36:43,213
have under the water?

655
00:36:45,297 --> 00:36:47,922
There is only one mystery
left on our countdown,

656
00:36:48,005 --> 00:36:51,380
and you don't want to miss it
because what was discovered

657
00:36:51,463 --> 00:36:56,463
just may be evidence of
an underwater alien base.

658
00:37:05,797 --> 00:37:08,880
On Ancient Aliens,
we've investigated

659
00:37:08,963 --> 00:37:10,880
the ocean's biggest mysteries

660
00:37:11,005 --> 00:37:15,505
for evidence of extraterrestrial
contact in the distant past.

661
00:37:15,547 --> 00:37:17,672
But recent satellite images

662
00:37:17,755 --> 00:37:20,630
may suggest that
otherworldly beings

663
00:37:20,713 --> 00:37:23,505
are inhabiting our oceans today.

664
00:37:24,463 --> 00:37:26,547
Number one on our list

665
00:37:26,630 --> 00:37:28,380
of the top ten
mysteries of the deep:

666
00:37:28,463 --> 00:37:30,797
Underwater Alien Bases.

667
00:37:35,380 --> 00:37:37,838
NARRATOR: With almost
200 miles of coastline,

668
00:37:37,922 --> 00:37:41,172
this picturesque region
is famous for its beaches,

669
00:37:41,255 --> 00:37:45,088
surfing and abundant sea life.

670
00:37:45,213 --> 00:37:46,922
It is also a hotspot

671
00:37:47,005 --> 00:37:51,422
for sightings of mysterious
lights in the water.

672
00:37:51,505 --> 00:37:53,922
BIRNES:
Folks have seen lights

673
00:37:54,005 --> 00:37:56,297
in the water outside Point Dume

674
00:37:56,380 --> 00:37:57,713
off the Malibu coast.

675
00:37:59,130 --> 00:38:02,338
There is this
very strange 911 call

676
00:38:02,380 --> 00:38:05,380
from an observer
near Point Dume,

677
00:38:05,463 --> 00:38:07,713
saying he saw a light
coming out of the water

678
00:38:07,797 --> 00:38:09,672
and calling it into
the sheriff's station.

679
00:38:10,838 --> 00:38:13,672
POPE:
One theory about this
trans-medium travel

680
00:38:13,755 --> 00:38:17,338
and these USOs
is that what we're seeing

681
00:38:17,422 --> 00:38:20,755
is evidence of underwater bases.

682
00:38:20,838 --> 00:38:23,880
They're operating here,
but under the oceans,

683
00:38:23,963 --> 00:38:25,588
right under our noses.

684
00:38:26,755 --> 00:38:29,797
NARRATOR:
While the idea of
underwater alien bases

685
00:38:29,880 --> 00:38:33,338
in Earth's oceans may
sound like science fiction,

686
00:38:33,380 --> 00:38:36,838
in 2014, satellite imagery

687
00:38:36,963 --> 00:38:40,172
revealed a very curious
formation on the seabed

688
00:38:40,213 --> 00:38:43,005
six miles off
the coast of Malibu.

689
00:38:44,213 --> 00:38:47,422
CHILDRESS:
The satellite photos
show what seems to be

690
00:38:47,505 --> 00:38:50,838
an oval, flat-topped structure

691
00:38:50,880 --> 00:38:55,380
that's got legs coming
down that are holding it up.

692
00:38:56,547 --> 00:38:59,755
It's about
2,000 feet underwater.

693
00:38:59,838 --> 00:39:04,088
POPE:
A lot of people got
very excited by this discovery.

694
00:39:04,172 --> 00:39:05,755
It's really quite striking,

695
00:39:05,880 --> 00:39:08,547
and it really does
look artificial.

696
00:39:09,672 --> 00:39:12,005
And it makes you
wonder, is this,

697
00:39:12,047 --> 00:39:14,547
as some believe,
an extraterrestrial base?

698
00:39:15,713 --> 00:39:18,672
NARRATOR:
Is there a connection
between the strange lights

699
00:39:18,755 --> 00:39:22,338
seen in the waters off
the coast of Southern California

700
00:39:22,338 --> 00:39:24,422
and the mysterious
undersea structure

701
00:39:24,547 --> 00:39:26,797
captured in the satellite image?

702
00:39:26,880 --> 00:39:30,422
For some scientists,
it's a distinct possibility.

703
00:39:31,963 --> 00:39:34,713
KAKU:
If all these objects
are buzzing our aircraft,

704
00:39:34,797 --> 00:39:38,005
they must have
a base of operations.

705
00:39:38,130 --> 00:39:40,713
But you see, if they have
a base of operations

706
00:39:40,838 --> 00:39:43,505
that's easily detected
by us humans,

707
00:39:43,588 --> 00:39:46,505
it would sort of defeat
the purpose of observing us.

708
00:39:46,630 --> 00:39:49,338
So, perhaps there's
an underwater base

709
00:39:49,380 --> 00:39:52,505
that is away from
prying eyes of humans

710
00:39:52,547 --> 00:39:55,547
so that we don't
interfere with their plans.

711
00:39:55,630 --> 00:39:58,088
That cannot be ruled out.

712
00:40:00,380 --> 00:40:03,297
NARRATOR:
While the formation
discovered deep in the ocean

713
00:40:03,380 --> 00:40:05,672
off the coast of Malibu
is highly unusual,

714
00:40:05,755 --> 00:40:08,005
it is not entirely unique.

715
00:40:10,005 --> 00:40:12,630
Across the globe,
mysterious anomalies

716
00:40:12,713 --> 00:40:14,880
have been detected on the seabed

717
00:40:15,005 --> 00:40:18,838
that some suggest are
underwater alien structures.

718
00:40:18,922 --> 00:40:21,713
The under ocean
geological survey

719
00:40:21,797 --> 00:40:24,547
determined that there were
dome-like structures

720
00:40:24,672 --> 00:40:27,963
between Cuba and
the coast of Florida.

721
00:40:28,047 --> 00:40:30,505
Was that a USO base?

722
00:40:31,547 --> 00:40:34,088
Because underwater,
underneath our oceans,

723
00:40:34,172 --> 00:40:36,588
best place,

724
00:40:36,713 --> 00:40:39,005
the very best place
to conceal yourself.

725
00:40:40,880 --> 00:40:43,338
COLLINS:
Absolutely anything
could be hiding within

726
00:40:43,463 --> 00:40:45,047
the oceans themself.

727
00:40:45,130 --> 00:40:48,797
And the depths of them
could hide vehicles,

728
00:40:48,880 --> 00:40:51,922
could even hide bases,

729
00:40:52,005 --> 00:40:54,463
uh, for hundreds,
if not thousands of years.

730
00:40:54,547 --> 00:40:56,672
We would not be aware
of their presence.

731
00:40:58,547 --> 00:41:00,047
CHILDRESS:
The oceans have everything

732
00:41:00,130 --> 00:41:04,422
that the crew of a ship
would need to survive.

733
00:41:04,505 --> 00:41:09,213
It's got plants and animals
that can be harvested for food.

734
00:41:09,297 --> 00:41:11,338
There's minerals and salt

735
00:41:11,422 --> 00:41:13,213
that can be taken
from the water.

736
00:41:14,463 --> 00:41:18,255
You can even
separate the hydrogen

737
00:41:18,338 --> 00:41:20,880
from the oxygen in the water

738
00:41:20,963 --> 00:41:24,213
to create fuels
and-and air to breathe.

739
00:41:25,880 --> 00:41:29,172
Everything that is
necessary for life

740
00:41:29,213 --> 00:41:31,463
can be found in the oceans,

741
00:41:31,547 --> 00:41:34,172
and it may be that
if extraterrestrials

742
00:41:34,297 --> 00:41:37,422
are in our oceans,
they're not just hiding there,

743
00:41:37,505 --> 00:41:39,713
this may be
their preferred environment.

744
00:41:43,672 --> 00:41:45,922
The idea that alien
bases might be hidden

745
00:41:46,005 --> 00:41:49,588
on the ocean floor
is incredibly thrilling.

746
00:41:50,630 --> 00:41:52,630
But while much of
the ocean's depths

747
00:41:52,630 --> 00:41:54,755
remain impossible to explore,

748
00:41:54,838 --> 00:41:57,547
ancient astronaut
theorists believe

749
00:41:57,630 --> 00:41:59,338
that the deeper we go,

750
00:41:59,380 --> 00:42:01,880
the closer
we'll get to the truth

751
00:42:01,963 --> 00:42:05,588
about mankind's
extraterrestrial past.

752
