NARRATOR: It is the Earth's most mysterious monument.
Megalithic stone columns that have stood
for an estimated 5,000 years.
Stonehenge is completely different
to anything else in the Neolithic world.
NARRATOR: But could Stonehenge have been something more
than conventional historians have assumed?
GIORGIO TSOUKALOS: The fact that we now know that Stonehenge
was part of a much larger superstructure
indicates we're facing a sensational mystery.
NARRATOR: And could modern scientific findings
reveal a startling truth?
HUGH NEWMAN: We don't really know who these people were,
don't really know where they come from.
WILLIAM HENRY: The people who built Stonehenge
just vanished from the Earth.
NARRATOR: Might the mystery of Stonehenge
be the key to unlocking the secrets of the universe,
and provide tangible evidence
of mankind's extraterrestrial past?
DAVID CHILDRESS: Is it possible that Stonehenge
was actually built by these sophisticated extraterrestrials?
It's a fantastic thought, but it's possible.
NARRATOR: There is a doorway
in the universe.
Beyond it is the promise of truth.
It demands we question everything
we have ever been taught.
The evidence is all around us.
The future is right before our eyes.
We are not alone.
We have never been alone.
Ancient Aliens S14E17 (" The Secrets of Stonehenge ") English HI/SDH CC Conversion SRT - UF (14.17)
NARRATOR: For six years,
the U.K. Ministry of Defence has been in a slow process
of releasing the entirety of their UFO files
to the National Archives of England.
Now the final batch of declassified reports
are released to the public.
Despite Ministry claims that no credible evidence
or alien craft was discovered in over 50 years of study,
one report, from January 14, 2009,
includes a fascinating photo of a disk-shaped craft
hovering above the world's most famous megalithic site:
Stonehenge.
Stonehenge has been the site of a number of UFO encounters
over the years.
The county of Wiltshire itself
is something of a UFO hot spot.
Dating back over the lifetime
of the Ministry of Defence's UFO project,
there have probably been several hundred,
if not low thousands, of sightings recorded
in the county of Wiltshire.
NARRATOR: But Stonehenge is not only a major hot spot
for UFO reports, it is also the center
of the crop circle phenomenon,
with dozens of unexplained crop formations appearing
in the area every year.
Many of the most spectacular formations
have appeared in that geographical area.
This is a location where there has been
more than, I suppose,
a fair share of weirdness over the years.
People are kind of obsessed by it,
because it's the only way they can get back
to have some contact with their ancestors.
I believe there's much, much more going on here.
NARRATOR: Why does the area of Stonehenge
experience more unexplained phenomena
than any other place on Earth?
Could a new examination of these massive stone blocks
reveal profound truths that have remained hidden
for more than 5,000 years?
The British Isles.
55 BC.
Julius Caesar begins a military campaign
to extend the Roman Empire into Britain.
His forces are met by ferocious resistance
from the native Celtic tribes, led by their Druid priests.
GRAHAM PHILLIPS: The tribes of Britain
were all united against the warring Romans
by the Druids,
to repel the greatest general who's ever lived.
NARRATOR: It would take the Romans nearly a century
to conquer Britain.
Once they succeeded, they turned Stonehenge
into a temple of their sun god, Apollo.
But the Romans were not the first to adopt this monument
as their own.
The Celts themselves had migrated into Britain
some 2,500 years before.
When they arrived, Stonehenge was already there,
but the country was eerily deserted.
The people who are responsible for Stonehenge, for erecting it,
are nowhere to be seen, and this is a puzzling,
uh, piece of information that we know now.
NARRATOR: Instead of ignoring Stonehenge
and building new temples, as historians would expect,
the Celts adopted it as their own.
You have to ask yourself:
Why did the Celts and Druids adopt Stonehenge
as a place of worship if they didn't build it?
Did they somehow know the power of the place?
NARRATOR: Archaeologists today believe
that this great Neolithic stone circle
has stood on the plains of Wiltshire, England,
for no less than 5,000 years.
An outer ring of 30 four-ton stones
surrounds five huge arches
whose massive blocks weigh 22 tons each,
and which were somehow transported
from 120 miles away.
It's an astonishing feat of ancient engineering,
and the mysteries about its construction still remain.
NEWMAN: Some of the stones at Stonehenge
weigh between 50 and 70 tons.
Some of the stones are even heavier.
So how could you have moved these into place?
How could you have moved them from Wales,
where the bluestones, the spotted dolerite, came from,
within Stonehenge?
PHILLIPS: The bluestones,
from which the original Stonehenge was constructed,
were transported from 120 miles to the west
from a place called the Preseli Mountains,
which is the only place in the British Isles
where you can get that kind of stone.
Now, how they were moved is a mystery.
NARRATOR: The predominant theory
as to how the megalithic blocks were moved is that the builders
fashioned sledges and rollers out of tree trunks
to lug the bluestones from the Preseli Hills,
then transferred them onto rafts
and floated them first along the Welsh coast
and then up the River Avon towards Salisbury Plain.
TSOUKALOS: You know, this idea
that all these ancient blocks were moved
with, uh, wooden rollers is...
is very interesting.
However, do you know what happens to wood
when you put 20 tons on a wooden roller?
It'll just get crushed to smithereens.
PHILLIPS: However they did it,
it must have been very important for them
to move these particular stones to Stonehenge.
And that's a mystery.
That doesn't happen anywhere else
at stone circles in the country.
They only come from stone that's quarried locally.
NARRATOR: However Stonehenge was constructed,
it involved moving much more than just the stone blocks
that stand today.
According to researchers,
this is just 25% of the original monument,
the center of a much larger structure
that was surrounded by multiple concentric circles
constructed over a period of more than a thousand years.
MARTINEAU: So Stonehenge is very interesting
in that it evolves over a very long period of time.
And the first thing that goes up at Stonehenge
is not there anymore.
It's the 56 holes
that today are known as the Aubrey Circle.
It used to be filled with the bluestones from Preseli.
PHILLIPS: Around the outside of the stone circle
is constructed a ditch and embankment.
This is the so-called "henge" structure
that stands around Stonehenge, from where it gets its name.
NARRATOR: Many mainstream scholars
suggest that Stonehenge was simply a place of worship
and a burial ground.
But why would the ancient people of Britain
have spent more than a thousand years
to build what amounts to a church and a cemetery?
NEWMAN: And the big problem is we don't really know
who these people were.
We don't really know where they come from.
So we find similar structures around the world
that show incredible levels of sophistication,
like the Pyramids of Giza in Egypt,
like Machu Picchu in Peru.
So why not, in ancient Britain,
why not have a very advanced civilization here?
The fact that we now know that Stonehenge was part
of a much larger superstructure
indicates to me that we've only barely scratched the surface.
What did it all mean?
NARRATOR: If the monolithic stones
that comprise Stonehenge today
are only merely a partial skeleton
of the original complex, is it possible
that it was among the most sophisticated structures
of the ancient world?
Perhaps the answers to who built it...
and why... can be found by examining similar structures
found all over the world.
NARRATOR: Dr. William Stukeley,
a pioneer in the field of archaeology,
begins the first scientific survey of Stonehenge.
He quickly notices that its axis aligns with sunrise
on the summer solstice.
Over the centuries, scientists discover that Stonehenge
also points to sunset on the winter solstice
and contains dozens of other astronomical alignments.
NEWMAN: Stonehenge is unlike any stone circle
anywhere on the planet.
It's perfectly circular. It has lintels above it.
It's designed with precision-engineered carving
and astronomical alignments.
TSOUKALOS: In my opinion, it is Stonehenge itself
that is the message.
And one part of that message is that Stonehenge
is a replica of our solar system on Earth.
Each circle corresponds with one of our planets
inside our solar system, including Pluto.
So, now we have a structure that's at least 4,000 years old,
and our ancestors knew about Pluto?
Without telescopes?
Someone told them about Pluto
and all of our planets in our solar system,
and that is the message, because in Neolithic time,
there is no way that they knew about this.
NARRATOR: Is it possible that the massive blocks
still standing at Stonehenge
were purposely arranged to reflect the positions
of the planets in our solar system?
And if so, could this astronomical knowledge
have been imparted to our ancestors by extraterrestrials?
While Stonehenge is the most extraordinary
stone circle in England,
in the 1970s, Scottish cartographer Alexander Thom
found that all the famed stone circles across the U.K.
have sophisticated designs that track the movements
of planets and constellations.
NEWMAN: Alexander Thom surveyed
over 300 stone circles in Britain.
And he came up with this principle
that they used advanced geometry in the construction,
which was connected with very advanced astronomy.
NARRATOR: Over time, archaeologists began to find
that ancient megalithic sites all over the planet
were built to align with the sun.
In Macedonia,
the Kokino Observatory features four stone thrones
at the top of a mountain
positioned to track the solstices and equinoxes.
In Machu Picchu, there is a stone temple
with three trapezoidal windows
also positioned to align with the sun
during the solstices and equinoxes.
On the northwest coast of France,
a collection of over 3,000 massive rocks,
called the "Carnac stones,"
align with both the summer and winter solstices.
And some of the sites where these solar alignments
are found include stone circles similar to Stonehenge.
The entrance to the Temple of Mnajdra
on the Mediterranean island of Malta
is aligned to mark both the solstices and equinoxes.
NEWMAN: In ancient Malta, going back
potentially to 3,000,
to 4,000 B.C. or even much older,
they also were observing
multiple different constellations,
including Taurus and others.
NARRATOR: As far as ancient astronaut theorists are concerned,
the most significant of all the ancient sites
that contain astronomical alignments
is also the oldest.
German archaeologist Klaus Schmidt begins
a major excavation at Gobekli Tepe.
This prehistoric site was believed
to contain a standard Roman-era cemetery.
But what Schmidt actually discovered would revolutionize
our view of the ancient world.
TSOUKALOS: Gobekli Tepe is one of the most fascinating stories
that we have in archaeology in recent times.
It is the first documented
and confirmed archaeological site in the world
that proves its age dating as far back
as 10,000 BC.
NEWMAN: Gobekli Tepe is the oldest known stone circle complex.
It dates to nearly 12,000 years old,
and it stands out as one of the most unique sites on the planet.
It really shouldn't be there at this date.
It wasn't for many thousands of years
that Stonehenge was built.
ANDREW COLLINS: Stonehenge in Britain was constructed
around 3000 BC, but
as much as 6,000 years earlier
in southeast Turkey,
Gobekli Tepe was built
by a very early form of Neolithic people.
And here you have a series
of circular monuments,
each made of T-shaped pillars,
like spokes of a wheel radiating out
from a central spot
where there are two huge monoliths
as much as 18 and a half feet tall.
NARRATOR: According to mainstream archaeologists,
one of the reasons that Gobekli Tepe has survived
in such remarkable condition for more than 10,000 years
is because it was deliberately buried.
But why?
Was it to protect it
from some catastrophic event?
Or was it to hide what ancient astronaut theorists consider
the structure's otherworldly origins?
Perhaps the answer can be found by a further examination
of not only who may have built Gobekli Tepe,
but why.
With stones weighing up to ten tons,
sophisticated carvings,
and even signs of hieroglyphic writing...
experts say Gobekli Tepe could only have been built
by an advanced civilization.
But according to mainstream historians,
the world's first true civilization...
the Sumerians... did not arise
until thousands of years after Gobekli Tepe was built.
BILL BIRNES: What we know about Gobekli Tepe
is that the Sumerians
said, "Oh, they were built by the ancients."
Who were the ancients that were here before the Sumerians?
So, we actually have geological artifacts
that point us to a civilization
before civilization.
NARRATOR: Ancient astronaut theorists suggest
Gobekli Tepe provides evidence
that a highly-advanced civilization flourished
long before the Sumerians.
And they suggest that a written record
of this civilization can be found in the Book of Enoch
and its mysterious tale of the Watchers.
HENRY: According to the Book of Enoch,
there was an ancient race of giants
who descended to the Earth.
They brought technology with them and shared it with humans.
They were called the Anunnaki,
also known as the Watchers,
extraterrestrial beings who lived near Gobekli Tepe.
TSOUKALOS: In the Old Testament,
there are quite a few passages that speak
of when the sons of God encountered the women of Earth.
They thought of them quite beautiful.
And so they mated with them,
and the offspring were the so-called giants.
NARRATOR According to the Book of Enoch,
these hybrid offspring were giants called the Nephilim.
They built a glittering high-tech civilization.
(thunder crashing)
But God considered them an abomination
and sent a great flood to wipe them out.
HENRY: Going back 5,000 years,
we have sacred texts that tell us
there was an antediluvian civilization.
There was a great flood and that there were survivors.
The Mesopotamians speak of this in The Epic of Gilgamesh,
the Egyptians speak of this in the Edfu creation texts.
We look around at temples and other constructions
that suddenly blossomed as if out of thin air.
We're asked to believe
that suddenly humanity learned the skills
for building these magnificent monuments
that we can't even duplicate today.
It doesn't make sense,
unless there was some pre-flood teacher indeed
that taught us how to do this.
According to some traditions,
some of the Nephilim survived the flood.
These hybrid children of the Anunnaki still knew
how to build megalithic monuments
aligned with the stars, and that's what they did.
NARRATOR: Tradition has it that after surviving the flood
and building Gobekli Tepe in Turkey,
the Nephilim began to migrate.
And each place they went,
they left stone circles in their wake.
COLLINS: After Gobekli Tepe,
there are other stone circles before we get to Stonehenge.
For instance, at Karahunj
in Armenia, there is a massive series
of megalithic constructions and circles
which have been dated to approximately 5500 BC,
according to the astronomical alignments.
Other sites that are of extreme age include
Cromlech Almendres in Portugal.
This dates back to around 6,000 years.
NARRATOR: If the Nephilim were responsible
for all these stone circles, is it possible that these giants
ultimately found refuge in the British Isles
and built Stonehenge?
Many believe that supporting evidence is found
in a 12th century book by Welsh cleric Geoffrey of Monmouth,
The History of the Kings of Britain.
It states that Stonehenge was erected by giants in Ireland,
then transported to its current site
by the famed magician Merlin.
JONATHAN YOUNG: The story has it, the king wanted
to honor the dead from a great battle,
and he wanted a particular monument
the giants had built in Ireland.
It was Stonehenge.
He sent Merlin to get this thing.
Merlin used magic to move it to Somerset.
This is how it got to where it presently is.
NEWMAN: And somehow he did this.
Whether it was magic, we really don't know.
But we do know that there are traditions
of giants moving stones.
CHILDRESS: We have to ask ourselves,
is it possible that the Nephilim,
as descendants of the Anunnaki,
were the actual builders of Stonehenge
and other megaliths in Great Britain?
And, in fact, uh, that may well have been the case.
NARRATOR: To further support the notion
that the Anunnaki not only built Stonehenge
but also other megalithic stone circles like Gobekli Tepe,
ancient astronaut theorists point to a curious legend
concerning a tribe known as the Tuatha Dé Danann.
TOK THOMPSON: The Tuatha Dé Danann
are probably the most important tribe
or figures or group of people...
if they are people... uh, that show up in Irish mythology.
The Tuatha Dé Danann were special.
CHILDRESS: The Tuatha Dé Danann were tall.
They had red hair and blue or green eyes.
They had magical powers.
NEWMAN: They had very advanced weaponry
and different types of what sounds like machinery.
But also they taught the high arts of civilization
and they were said to be almost like the Shining Ones
of the biblical tradition.
NARRATOR: Could it be
that the Tuatha Dé Danann were the descendants
of the otherworldly beings described
in the Sumerian tradition as the Anunnaki?
Ancient astronaut theorists say yes.
And as evidence,
they point to a curious historic fact.
The Tuatha Dé Danann, or tribe of Danann,
originally had a different name,
the Tuatha Dé Anu.
CHILDRESS: The name means "the tribe of Anu.".
And Anu here is the Anunnaki.
It's this mysterious people
who are talked about in Sumerian texts.
So, here we now have a connection
with the Tuatha Dé Danann
with the Anunnaki of ancient Sumeria.
NARRATOR: Did these Anunnaki descendants
really migrate to the British Isles
and ultimately build Stonehenge?
And if so, could this shed light
on the mystery of not only who built Stonehenge but why?
Perhaps further clues can be found
by examining a startling new genetic study
that indicates that,
almost immediately after Stonehenge was built,
its builders
mysteriously vanished from the Earth.
NARRATOR: In a groundbreaking genetic study,
published in the journal Nature,
Harvard researchers announce a stunning discovery
about ancient human DNA.
It reveals that,
immediately after Stonehenge was built,
the people who built it,
the ancient inhabitants of Britain,
suddenly and almost totally vanished from the British Isles.
They left behind virtually no DNA
in the modern British population.
What the 2018 study suggests
is that the genetic signature of the Neolithic inhabitants
of the British Isles,
it vanishes shortly after the period
in which they build Stonehenge and is largely replaced
by an entirely new human culture
in a very short amount of time.
HENRY: The Harvard study is an absolute bombshell.
An entire civilization just disappears without a trace,
vanishes into thin air?
It's easily the most surprising and most shocking conclusion
you can imagine.
NARRATOR: The study used
a revolutionary new technique
that samples DNA from ancient human bones
and then compares it to the DNA
of modern people in the same place.
Scientists then determine
what percentage of the modern population
is descended from the ancient group.
So, the new genetic data are really providing
an example of population replacement,
in which the genetic markers that characterize one population
is almost entirely replaced in a relatively short amount of time
by the genetic signature that characterizes another population
from a different part of the world.
NARRATOR: The strange disappearance
of the Stonehenge builders
remains a profound historical mystery.
But historians had long known that around 2500 BC,
just after Stonehenge was built,
a new group entered the British Isles.
The so-called Beaker people are named
for their distinctive clay pottery
and are believed to be the ancestors of the Celts.
CHILDRESS: You might think that
when the original population of Britain suddenly left
these stone monuments,
that the newcomers would maybe just let them
go back to nature and ultimately just-just fall down
and be destroyed, uh, over time.
But that's not what happened.
And so it would seem that these newcomers
realized that these places had power.
There was an energy associated with them.
Something important.
NARRATOR: The Orkney Islands, Scotland.
2019.
Ancient astronaut theorist Andrew Collins
and author Graham Phillips
have come to these islands to investigate
the mysterious disappearance of the people who built Stonehenge.
Dating back to 3200 BC,
Skara Brae was buried in sand for thousands of years
until a great storm uncovered it in 1850.
Now known as the Scottish Pompeii,
it was home to the people
who began Britain's stone circle building boom,
ultimately built Stonehenge,
and then mysteriously vanished from the genetic record.
Right. Site's over here.
Well, it's quite amazing
that this place was completely covered
with sand,
uh, until they refound it in the 19th century.
The people who built the first stone circle
a couple of miles from here lived here.
Yeah. Just look at this place.
I mean, it's just extraordinary.
PHILLIPS: It's pretty sophisticated.
I mean, these walls here
are really quite advanced for 5,000 years ago,
when everybody else in the country was living in,
well, mud huts, basically.
I know. And-and the incredible thing about this is
the descendants of these people end up creating
all of the stone circles around Britain.
How do you think this started?
I-I think something was changing in the minds of these people.
But, you know, the bigger question is,
what were they doing here?
NARRATOR: Experts believe that the descendants of Skara Brae
began building the great stone circles
that ultimately led to Stonehenge.
To see the first of these mighty circles,
Andrew and Graham travel six miles south.
So, we're going now to the Stones of Stenness,
which is the first stone circle, that we know of,
built anywhere in the British Isles.
It originally consisted of
12 stones in a circle
around 100 feet in diameter,
and the stones are up to 16 feet high.
COLLINS: What's so incredible
is that this first stone circle in Britain
has a relationship
with Gobekli Tepe in southeast Turkey, which...
because the Stones of Stenness
is aligned to the stars.
To the south,
it's the rising of the stars of Orion.
And to the north,
it is the setting of the stars of Cygnus.
And the very same constellations feature
within astronomical alignments at Gobekli Tepe,
thousands of miles away.
NARRATOR: If the Stones of Stenness,
like Gobekli Tepe, Stonehenge,
and other megalithic structures,
was constructed in such a way as to be in alignment
with astronomical events, why?
Was it to merely function as a type of calendar,
indicating when to plant crops or perform rituals?
Or were these structures oriented to the stars
for a far more profound
or perhaps extraterrestrial purpose?
It is true that-that Stonehenge can be used
or was used as a calendar.
There is no doubt about it.
However, in order to create a calendar,
there was absolutely zero need
to build a megalithic structure as gigantic as Stonehenge.
'Cause you could have recreated the entire same thing
by, essentially, placing ordinary sticks in the ground.
That was not the case.
So what was it?
POPE: There is a knowledge and purpose here,
and it's-it's sophisticated.
Were ceremonies and rituals
conducted there that actually achieved something?
In other words, is, in one sense,
Stonehenge a device, a machine?
MARTINEAU: This geometry is there right from the beginning
of the stone circle building
and the reason they were choosing these shapes
was something to do with astronomy.
And I think it's some kind of interesting technology,
ancient technology, um,
whose origins are lost in the mist of time.
NARRATOR: Is it possible
that the builders of ancient stone circles
weren't constructing giant celestial calendars,
but, instead, were using the sun and stars as guides
so that the giant stones they were using
could be precisely placed?
As far as ancient astronaut theorists are concerned,
the answer is a profound yes.
And they believe the precise astrological placements of these
weren't intended for ritual purposes,
but for technological ones, possibly as a means
of conducting and generating
a type of geo-electrical energy.
So the people who built this,
you think, were inspired by the descendants
of those who built Gobekli Tepe.
I'm certain of it.
But as we know,
this is the beginning
of something brand-new that starts here
on the Orkney mainland and continues to Stonehenge.
So what comes next?
NARRATOR: Just down the road from the Stones of Stenness
lies the Ring of Brodgar.
The third largest stone circle in the British Isles,
it is a hotbed of UFO sightings and activity.
According to ancient astronaut theorists,
it could also hold the key to solving the mystery
of why the Stonehenge builders suddenly
and inexplicably... disappeared.
NARRATOR: On Scotland's Orkney Islands
ancient astronaut theorist Andrew Collins
and author Graham Phillips
are investigating stone circles
that are believed to be even older than Stonehenge.
They have just arrived at the Ring of Brodgar,
which is not only an important historical site
but also a hot spot for UFO sightings.
PHILLIPS: We're here at the Ring of Brodgar.
It is a henge circle, so all around
the outside of it is a ditch and embankment.
COLLINS: And one of the things that's been repeatedly found
in connection with stone circles
is that there's a very special geology associated
with the landscape around them.
And all of these seem to be able
to manifest mysterious lights.
And they almost appear to act
like windows onto another realm.
Because as you get higher,
you can see that the whole place is like a perfect circle.
A perfect hole out of this reality
into another realm all together.
So this place here could actually be
some kind of portal between this world and another?
Precisely.
But what's so incredible
is that at virtually every location
that this megalithic culture moved out
is also somewhere associated with the appearance
of mysterious lights, what we'd call UFOs.
We're talking about Stonehenge,
Avebury,
the Isle of Anglesey in Wales,
and the area around the Rod Stone.
All of these locations
are what we would call portals,
places where mysterious lights appear
and then disappear.
NARRATOR: Is it possible that ancient stone circles
found throughout the world were once used as portals
to other parts of the universe?
And could this explain why the builders of Stonehenge
suddenly disappeared from the DNA record,
right after the structure is believed to have been completed?
While such a notion may sound preposterous to some,
ancient astronaut theorists suggest
that it is far from impossible.
NEWMAN: They realized that these stone circles
actually do manipulate earth energies,
these currents that are part of the magnetic field.
CHILDRESS: Archaeologists now
are speculating that the blue stones
that are part of the Stonehenge complex,
they are a type of black-blue dolerite
that has very bright nodes of quartz in them.
NARRATOR: Quartz is able to convert
the earth's natural electrical vibrations
into a form of energy.
The amount of energy increases
when the quartz is under pressure,
as it would be as part of a massive monolithic structure
like Stonehenge.
NEWMAN: So you have electrical qualities
when the quartz is kind of crushed
and then you have magnetic qualities as well
within the same stone.
So this could have been used
to manipulate earth energy currents.
CHILDRESS: Many of the stone circles
have something to do with astronomical alignments,
and you have to wonder if it's a way of calculating
and having a calibration that you can use
to create a special portal area.
It's got a special energy, perhaps,
that's being manipulated
and created by these megalithic structures.
NARRATOR: Did the builders of ancient megalithic structures
like Stonehenge and Gobekli Tepe,
use their advanced knowledge
of the interconnectivity between the Earth...
and the ability of precisely placed megalithic stones...
to generate energy to create portals?
And could this be why they decided
to quarry the rock for Stonehenge
from 120 miles away,
because they needed a particular type of rock
with a particular quartz concentration?
If so, could their incredible ability
to create energy be an indication
that their origins might be extraterrestrial?
If the Nephilim were actually
some sort of extraterrestrial race
with super high technology, then maybe
now all the high-tech stuff is gone
and all that's left is this skeletal structure
that we call Stonehenge.
NARRATOR: If the builders of Stonehenge
really did create a portal
through which they returned to the home planet
of their extraterrestrial ancestors,
did that portal close after they left?
Or was the site stripped of its power
when the original structure was deconstructed?
Perhaps the answer can be found
by examining one of the strangest events to occur
at Stonehenge in modern times.
An event that some believe may contain a message
from another world.
NARRATOR: Wiltshire, England.
July 1996.
One of the most complex
and spectacular crop circle designs ever seen
appears in a field opposite Stonehenge.
POPE: The so-called Julia Set
appeared right next to Stonehenge.
Now, the Julia Set takes its name
from a fractal, which is a mathematical shape.
This was intricate, complex.
There's an interesting story
that apparently a taxi driver
saw this formation
just appearing suddenly, magically,
as if some unseen hidden force
was making the pattern.
Some people have said that they were symbols
that are meant to convey information.
And it's the conveying of information
that I think is the important thing here.
That really might be the key
to unlocking the mystery here.
NARRATOR: Could it be that the incredible crop formation
that appeared next to Stonehenge
was a message from extraterrestrial visitors?
If Stonehenge was built as a portal to the stars,
can this technology be reactivated?
And might the mathematical information contained
within the Julia Set provide the key
to reopening the portal?
CHILDRESS: When we look at Stonehenge,
we have to wonder about the energy there.
So, early on, it becomes a site where things are happening,
extraterrestrials are landing here perhaps.
But it all starts with some activity early on
in this, in this special place.
People speculated that the ancients
were able to perceive power,
Earth energies, mysterious forces
that perhaps modern humans
have lost the ability to perceive.
Maybe, the theory is, that we've got smarter in other ways,
but we've lost a certain something,
the ability to perhaps tap into
these ancient power sites.
NARRATOR: Does a megalithic stone circle
standing alone in the English countryside
represent the remains of the most sophisticated technology
to ever exist on Earth?
A technology which was part of a vast global network
of similar structures that were not only capable
of generating vast amounts of energy,
but also the means by which alien visitors
could both arrive and depart?
Perhaps the stones that still remain
were deliberately left standing
so that humankind would one day restore
this lost technology...
