1
00:01:11,120 --> 00:01:14,600
This could be considered
a lost technology.

2
00:01:23,400 --> 00:01:26,480
It's impossible. It's impossible.

3
00:22:36,280 --> 00:22:40,080
Twenty years from now,
all the forest will disappear.

4
00:22:54,600 --> 00:22:58,040
I was arriving in Rio Branco by jet,
commercial jet.

5
00:22:59,040 --> 00:23:00,880
- Sitting in the window seat.
- Yeah.

6
00:23:00,960 --> 00:23:03,280
- And looking at the environment like this.
- Yes.

7
00:23:03,360 --> 00:23:04,680
Like this.

8
00:23:04,760 --> 00:23:06,760
And then I see a big circle.

9
00:23:15,080 --> 00:23:17,520
My God. What's this? Huh?

10
00:23:17,600 --> 00:23:19,960
- And the jet is so fast. Gone.
- Yeah.

11
00:23:20,800 --> 00:23:21,680
Disappear.

12
00:23:55,040 --> 00:23:57,400
Fantastic design. And so big.

13
00:23:58,400 --> 00:24:00,600
- So enormous. Enormous.
- Yeah. Yeah.

14
00:24:14,560 --> 00:24:16,000
Ah, look. Another one.

15
00:24:16,720 --> 00:24:19,920
- Yes. They're everywhere.
- Everywhere.

16
00:24:20,960 --> 00:24:22,000
Another one here.

17
00:24:22,880 --> 00:24:23,960
Another one here.

18
00:26:02,440 --> 00:26:05,200
- The first one was a famous archaeologist.
- Yes.

19
00:26:05,280 --> 00:26:07,680
- I showed her the picture…
- Yeah. Yeah.

20
00:26:07,760 --> 00:26:13,520
…and she looked and said, "Where is it?
In the Amazon? It's impossible."

21
00:26:14,320 --> 00:26:17,160
It's impossible? Look at the picture.

22
00:26:17,240 --> 00:26:18,080
Help me, please.

23
00:26:18,160 --> 00:26:19,880
- I don't know what this is.
- Yes.

24
00:28:53,640 --> 00:28:56,800
I think so
because many of these are so complicated.

25
00:28:58,000 --> 00:29:02,080
{\an8}It is necessary to have pre-planned
how to do it and how to organize it.

26
00:29:29,160 --> 00:29:31,160
This area is full of roads.

27
00:29:31,240 --> 00:29:35,000
- Hunters and gatherers do not build roads.
- Mm-hmm.

28
00:29:36,920 --> 00:29:42,000
It needs already society
with a much more higher level of thinking.

29
00:29:42,080 --> 00:29:45,360
- I see.
- And relationships between each other.

30
00:29:45,440 --> 00:29:48,120
- So that is a really complex society.
- Yeah.

31
00:29:51,160 --> 00:29:54,920
No, it was totally a… surprise for us.

32
00:30:13,480 --> 00:30:17,680
From Tequinho,
we found 40,000, uh, shards of ceramics.

33
00:30:33,480 --> 00:30:36,640
- Most of it is of high quality…
- Right.

34
00:30:36,720 --> 00:30:39,360
- …and polychrome ceramics.
- Right.

35
00:30:42,440 --> 00:30:46,760
Yes, normally polychrome ceramic is
considered to be part of civilization.

36
00:31:12,680 --> 00:31:14,040
I think you're right because

37
00:31:14,120 --> 00:31:17,920
this Geoglyph culture
is exactly the same time

38
00:31:18,000 --> 00:31:21,600
when the Greek culture had
archaeological period

39
00:31:21,680 --> 00:31:24,760
that has been called
Geometric Greek period.

40
00:32:47,720 --> 00:32:52,120
That's a very good question
because we excavated up to one meter…

41
00:32:52,200 --> 00:32:55,200
- Mm-hmm.
- …and after that, the ceramic disappeared.

42
00:32:55,280 --> 00:32:58,720
But then I noticed
that the charcoal continued.

43
00:32:59,720 --> 00:33:02,240
And we went down and down and down,

44
00:33:02,320 --> 00:33:06,640
and then we started to take
radiocarbon samples,

45
00:33:06,720 --> 00:33:10,840
and finally we found
that many of these sites

46
00:33:10,920 --> 00:33:14,360
have been established already
10,000 years ago.

47
00:33:18,480 --> 00:33:20,800
- From the deep past, exactly.
- Yeah. Fascinating.

48
00:35:07,160 --> 00:35:11,440
Our understanding stopped
on the border of the forest,

49
00:35:11,520 --> 00:35:13,720
and now we want to know what's there.

50
00:35:27,040 --> 00:35:32,080
By using this system,
we can clear the vegetation out

51
00:35:32,160 --> 00:35:35,280
and get the results from the bottom.

52
00:35:35,360 --> 00:35:39,280
And in that way,
we can see the topography exactly.

53
00:35:59,560 --> 00:36:02,120
We are going to fly at 80 meters.

54
00:36:02,200 --> 00:36:03,240
{\an8}That's good.

55
00:36:03,320 --> 00:36:08,640
{\an8}Maybe we can have
about 100 to 200 points per square meter.

56
00:36:08,720 --> 00:36:09,960
That's excellent.

57
00:36:10,040 --> 00:36:12,600
The topography will be very precise.

58
00:36:43,560 --> 00:36:46,600
These drones will change everything
in archaeology.

59
00:37:46,080 --> 00:37:53,040
whose origins are closely tied to nature,
to the earth.

60
00:37:59,600 --> 00:38:01,960
I am standing in a place

61
00:38:04,200 --> 00:38:07,320
for which I have the utmost respect.

62
00:38:08,520 --> 00:38:11,680
For us, it is a sacred place.

63
00:38:11,760 --> 00:38:16,080
It wasn't made for war.
It wasn't made for defense.

64
00:38:16,160 --> 00:38:21,200
It was made to express something cultural.

65
00:38:37,880 --> 00:38:42,080
So, we compare this here

66
00:38:42,160 --> 00:38:47,960
as if it were a circle of the Apurinã

67
00:38:48,040 --> 00:38:54,120
when they dance and pay homage
to a deceased chief, a shaman,

68
00:38:54,600 --> 00:38:57,680
to an important person
from the village who has died.

69
00:39:01,600 --> 00:39:06,160
We see this space as somewhere
that would welcome us

70
00:39:06,920 --> 00:39:13,040
once we have left the material world.

71
00:40:38,400 --> 00:40:40,760
We surveyed the area using the LiDAR.

72
00:40:41,360 --> 00:40:43,920
And you see the trees?

73
00:40:48,120 --> 00:40:49,160
And now…
