All language subtitles for HISTORY CHANNEL - Ancient Aliens (2014) - (S08E02 - Mysterious Structures) BD 1080p

NARRATOR:
Mysterious stone heads...

MAN: How in the heck
did they make these?

Where did they come from,
and how did they move them?

NARRATOR: Ancient monuments
containing 100-ton blocks...

DIFFERENT MAN: Some of the
stones are of such magnitude,

modern machinery is incapable
of putting them there.

NARRATOR: And solid granite
cut with incredible precision.

DIFFERENT MAN: We ourselves
today could not replicate

what our ancestors allegedly
accomplished with stone masonry.

NARRATOR: Throughout the world,

there are giant structures that
have baffled archaeologists.

Could they really
have been constructed

using primitive tools,

or might they be the product
of alien technology?

DIFFERENT MAN: Extraterrestrials
would not have left

without any proof.

They wanted that
in the far future,

we start to reflect, "Have we
been visited by outer space?"

NARRATOR: Millions of people
around the world believe

we have been visited in the past
by extraterrestrial beings.

What if it were true?

Did ancient aliens really help
to shape our history,

and, if so, might they have
a connection

to the world's most
mysterious structures?

On the northwest coast of
France, just south of Brittany,

lies one of the most important
prehistoric sites in Europe.

At the seaside village
of Carnac,

over 3,000 megalithic stones

are placed in rows
over two miles long.

The Carnac stones were hewn
from local rock formations

and erected between
4500 to 2500 BC

at the end of the Stone Age.

They are the largest collection
of standing stones in the world.

Archaeologists are baffled

by the many megaliths
at Carnac here.

It's clearly a massive
construction project

with blocks of granite
weighing 50 to 100

to even up to 350 tons.

Legends here say
that giants built Carnac,

but you have to wonder,
what is the real purpose

of these giant megaliths,
and why would prehistoric people

have moved all of these
massive stones and placed them

in the many alignments
here at Carnac?

MAN: Thousands of large stones
have been arranged

in very interesting patterns.

They're arranged in intersecting
lines that form triangles

that could only be visible
from above the earth.

These arrangements of stones
may have been a way

of communicating
with extraterrestrial beings.

NARRATOR: The ancient Greek poet
Pindar spoke of a mystical land

called Hyperborea
far to the north

where the sun shined
24 hours a day.

Legends claim that Apollo
visited Hyperborea,

traveling in his chariot of fire
every 20 years.

MAN: Apollo would tell
to the Greeks,

"OK. I'm gonna go see
some other people."

"I've got to go and teach them,"

and they're like,
"Well, where are you off to?"

and he's like, "Well,
I'm actually going to a place"

"that's beyond where
the north wind comes."

"It's the land
of the Hyperboreans."

NARRATOR: Although mainstream
archaeologists speculate

that the Carnac stones
are most likely tomb markers,

ancient astronaut theorists
believe these stones

are intentionally laid out
in a unique geometric formation.

Many speculations
existed since centuries,

and only a few years ago
in France,

they started to photograph
this whole French Brittany

by helicopters, and when
they put the pictures together,

all of a sudden,
someone realized,

"Hey, this is not coincidence."

The distances of the lines
are always the same...

2,860 meters

or exactly the half
of 2,860 meters.

The angles are always the same.
It's Pythagorean triangles.

It's all a gigantic geometrical
pattern from Stone Age,

which is impossible.

Our Stone Age people had no idea
of Pythagoras' triangles.

Pythagoras was about 420 BC.

NARRATOR: Even though
the geometric arrangement

of the Carnac stones predates
the Pythagorean theorem

by more than 2,000 years,
one question remains...

Why were the stones arranged
in such a precise pattern?

CHILDRESS: The Carnac Stones
are one of the few things

on the planet that can
actually be seen from space,

and they're a perfect marker
for any kind of aerial vehicle

looking down on the earth.

Many of the tourists
who come here to Carnac claim

that they can actually
feel the energy emanating

from these granite megaliths.

How did these ancient people
know about this energy,

and is it possible that they
were able to use this energy

to even move and erect
these giant stones?

VON DANIKEN: I am of the opinion
that they were made on purpose.

The extraterrestrials told our
ancestor, "Do this and this."

It's not the extraterrestrials
who made the stone lines.

It's the humans who made it

but by the order
of the extraterrestrials.

NARRATOR: But were
the Carnac stones a signpost

for an ancient astronaut
called Apollo

as he flew his spacecraft
high above the land?

CHILDRESS:
If the Greek god Apollo

was really some kind
of ancient astronaut,

it's possible that the stones
here at Carnac

were a directional finder
pointing the way

to the far north, to the
Hyperborea of the ancient gods.

NARRATOR: Over 1,000 miles north
of Carnac lies Scandinavia,

home to an ancient people
called the Norse.

The Norse were tribal
Germanic people who lived

in what is now known as Sweden,
Denmark, Iceland, and Norway.

Norse legends record
the triumphs of great warriors

with advanced weaponry,
sophisticated combat techniques,

and navigational prowess.

Like the Greeks, Norse mythology
includes supernatural beings...

other worlds,
and powerful gods...

but like the Romans,

could the Norse myths refer
not to different gods,

but the same gods as those
depicted by the ancient Greeks?

CHILDRESS: There are
a number of similarities

between Greek mythology
and Norse mythology,

and many of the gods
are almost identical,

and they do much the same thing.

NARRATOR: Descriptions
of the Viking god Odin...

The god of war, death,
and knowledge...

And the Greek god Zeus
bear striking similarities.

Zeus and Odin
are both sky father gods.

They travel through the skies
in chariots

because they are akin
to the solar divinities.

The precursor to many religious
beliefs is sun worship.

The ancients knew
that life came from the sun.

So that is a great mystery
and a source of great awe.

What you're getting there is not

just some minor deity,
but you really are

nailing it down to one
of the chief deities.

This is a very important
character,

and so whoever
is behind Odin or Zeus

is obviously a person
or a divine entity

which is shared
by these cultures,

and it's clear that whoever
inspired the myth of Zeus

or Odin is somehow somebody
who had an extremely important

contribution to make
to both civilizations.

So this entity was definitely
known throughout Europe.

NARRATOR: Could the Norse
and Greek gods really have been

the same
extraterrestrial beings?

Did they use the megalithic
stones at Carnac

as a directional marker
that could be seen

from high above the earth,
and, if so,

is it possible that this site
and other megalithic structures

around the world really
were built with the help

of otherworldly technology?

Ancient astronaut theorists
say yes and claim further proof

can be found by examining
megalithic rocks in Bolivia

cut with incredible precision.

NARRATOR:
Palm Springs, California.

Master stonemason and sculptor
Roger Hopkins

uses a variety of advanced tools
to cut and shape hard stones.

Powered implements
such as diamond-tipped wires

and polishers enable him
to fashion works of art

out of huge granite blocks
obtained from nearby quarries.

Yet even with these
high-tech tools,

Hopkins cannot replicate
what ancient civilizations

accomplished
thousands of years ago.

Could these advanced engineering
methods be the smoking gun

that proves humans had help
from alien beings?

HOPKINS: The precision
on some of the work

that I've seen
is just incredible.

It's possible to do by hand,

but it'd take
an incredible amount of time.

Plus, you have to have
years of experience

to be able to pull it off.

TSOUKALOS: In my opinion,
the most tangible pieces

of evidence
that we have regarding

possible extraterrestrial
technology is when we look

at the ancient
stone-cutting techniques

because in some instances,
we ourselves today

could not replicate
what our ancestors

allegedly accomplished
with stone masonry.

NARRATOR: Puma Punku
is a large temple complex

located on a high plateau
in Bolivia.

( Sheep bleating )

Mainstream archaeologists
date the site

from approximately 200 BC.

The people who lived here
had neither a written language

nor the wheel,
yet somehow they built

one of the world's
most complex structures.

Ancient alien theorists
view Puma Punku

as clear proof
of extraterrestrial influence.

TSOUKALOS: The ruins
we find at Puma Punku

are simply extraordinary.

Puma Punku defies logic.

COPPENS: The interest
of Puma Punku is not so much

that the individual stones
sorted together perfectly,

but the fact that
the stones, as such,

are of such tremendous design
that it requires concepts

of mathematics which
are far beyond anything

we are actually using right now.

Yet somehow in the past,
somebody has made that

for a specific purpose
and in a way

which even computer programs
today would kind of go,

"How is this possible?"

TSOUKALOS: In the highlands
of Bolivia, Puma Punku,

some of these blocks
are over 40 to 50 tons each.

What can you tell us about this?

HOPKINS: Boy, they had
their stone-cutting abilities

pretty well fine-tuned
for 5,000 years old.

I mean, it's almost
unbelievable,

but these cutting planes
that they have on here

are very impressive,
and some of the incise cuts,

see, like in here,

all these interior cuts,
very hard to do.

I mean, it would be difficult
for us with our equipment

to get that kind of precision.

TSOUKALOS: Let's talk
a little bit about inside boxes.

Ooh, I was afraid you were gonna

pull something like this on me.

That is a hell
of a piece of work.

I mean, if we were to do
something like that today,

we'd use what they have, these
computer-driven CNC machines

which have diamond tips,
and you have a template

that the computer follows,
and even then,

it may not come out as perfect.

TSOUKALOS: Because,
even though you can tell

that, obviously,
this piece broke off...

HOPKINS: Mm-hmm.

TSOUKALOS: Nowhere in here
can you see any imperfection,

and, by the way,
when you're there,

if you go with your finger
over these edges

and you put a little pressure
on your fingertip,

you can cut yourself.

This is how sharp the edges are.

NARRATOR: But where could
the ancient peoples

have developed such technology?

Is it really possible
that extraterrestrial visitors

provided different
construction methods and tools?

When I saw these blocks,

I didn't really think
that they were cut.

The first thing, really,
that I thought of was,

this appears very similar
to Frank Lloyd Wright's

textile block system
of construction which he used

in his California houses
in the early 1920s.

Now, what he did was, he took
concrete, poured it into molds.

TSOUKALOS: There actually
are ancient Incan legends

that suggest that they
had the capability

of softening the stone.

At Sacsayhuaman, for example,

we find these
gigantic stone blocks,

gigantic stone walls where
it looks as if those stones

were molten, put into place, and
then the stone hardened again.

NARRATOR: Is it possible
that the precision-cut stones

at Puma Punku
are really the product

of extraterrestrial technology?

Perhaps further clues can be
found halfway around the world,

with an ancient civilization
that was found

buried beneath the earth.

NARRATOR:
Located more than 500 miles away

from the crowded streets
of Istanbul

is Sanliurfa
in southeastern Turkey.

There in 1994
on a dusty hilltop,

a local shepherd noticed
the tip of a stone

sticking out of his field.

He began to dig, eventually
unearthing a 19-foot pillar.

Its edges were precise,
and rising from its center

was a relief carving
of a strange animal.

Upon closer examination,
it appeared

that the finely chiseled stone
had been fashioned

by talented stonemasons
working with advanced tools.

When word of the discovery
reached

the scientific community,
one fact became obvious...

A Kurdish shepherd had stumbled
upon what is perhaps

the most astonishing
archaeological discovery

in modern times,
a site known as Gobekli Tepe.

WOMAN: For 13 years,
a German archeology team

has been meticulously
going into a hill,

and they have been doing carbon
dating as deep as they go.

It has taken them 13 years
to uncover

only five percent
of a gigantic civilization.

They know
what's under the ground...

Circles upon circles
upon circles,

perfect circles in stone...
And rising up

out of those stone circles
are huge sculpted columns

19 feet high,
15 tons per column.

NARRATOR: Test results
have supported the idea

that Gobekli Tepe
is nearly 12,000 years old,

almost 7,000 years older than
Mesopotamia's Fertile Crescent,

long heralded
as the cradle of civilization.

HOWE: In Gobekli Tepe,

the oldest advanced site now
on our planet.

We know of no other site
that is this advanced...

and it has now doubled
the history of humanity.

MAN: And right there
is this gigantic site

with huge megalithic
circular structures.

It just stands there,
a mystery asking us

to go figure how was this done.

What's the background to this?
We don't know who made them.

They just come
out of the darkness

of the last ice age,
where we know nothing

and enter the stage of history
already fully formed,

and, to my mind,
this is indicative

of a major forgotten episode
in human history.

NARRATOR: Curiously,
after 13 years of digging,

archaeologists investigating
the ancient site

have failed to recover
a single stone-cutting tool.

Nor have they found
any agricultural implements.

HOWE: How in the world
can you contemplate

19-foot-tall,
perfectly sculpted columns

that are 11,000 to 12,000
years old and no tools?

NARRATOR: The mystery
of Gobekli Tepe

is further compounded
by the ancient stone carvings

found throughout the site.

They depict creatures
like wild boars and geese.

MAN: We see various types
of creatures, different animals,

birds, insects,
and even abstract human forms

that seem to come together to
create this very weird menagerie

which has totally baffled
the archaeologists

who have uncovered this site.

Now, what they represent
is a matter of speculation,

but it's my intuition

that they may even represent
a ark in stone.

NARRATOR: Located less than
350 miles from Mount Ararat,

the site many biblical scholars
believe to be the resting place

of Noah's Ark, the animal
carvings of Gobekli Tepe

suggest a time
in the region's history

when the indigenous
animal population may have been

of a totally different origin,
but do these carvings

actually provide
historical proof

of the great flood
that was described in the Bible?

HANCOCK: Archaeologists
are aware that there are

more than 2,000 myths
of a great flood

which destroyed
an earlier civilization.

NARRATOR: Some researchers
theorize that the events

of a cataclysmic flood
and a story similar

to that told of Noah's Ark
was recorded

on the stone pillars
of Gobekli Tepe.

If true, that would push
the date of the great flood

back to the end
of the last ice age,

far earlier
than the biblical period.

COLLINS: There is evidence
that this may have ended

quite catastrophically.

There was a lot of things
happening,

a lot of migrations, possibly
waters rising up very quickly,

a lot of rapid changes
in lifestyles.

NARRATOR: But another perhaps
even more profound question

remains... who built Gobekli Tepe,
for what purpose,

and how did such
an ancient site remain

in nearly pristine condition
for more than 10,000 years?

COPPENS: In the case
of Gobekli Tepe, we find

that the site was carefully
placed underneath sand.

This site was buried.

It appears as if somehow
the usage of Gobekli Tepe

was no longer there
and that people moved on

but had such a reverence
to this important site

that rather than destroy it,

they put it to peace
by burying it.

NARRATOR: Is it possible
that the people at Gobekli Tepe

had such reverence for the site
because it really was built

with the help
of alien technology?

Ancient astronaut theorists say
yes and claim further evidence

that extraterrestrials
were behind the construction

of the world's most mysterious
structures can be found

in Lebanon by examining
a site that dates back

nearly 9,000 years.

NARRATOR: Eastern Lebanon,
the Beqaa Valley.

Here at this archaeological site
stand the ruins of Heliopolis,

built in the fourth century BC
by Alexander the Great

to honor Zeus, but beneath
the Corinthian columns

and remnants of both Greek
and Roman architecture

lie the ruins of a site
that is much, much older.

According to archaeologists, it
dates back nearly 9,000 years,

the ancient city of Baalbek,

named after the early
Canaanite deity Baal.

WOMAN: Baal is the god of life,

the god of the sky,
the god of the sun.

He was the god that was
venerated on the site of Baalbek

during the Canaanite
and the Phoenician times.

MAN: And so, because it was
already sacred to the god Baal,

then later the Greeks
and the Romans

then would build temples
on this very same spot.

NARRATOR: Archaeological surveys
have revealed

that the enormous stone
foundation that lies

at the base of the site dates
back tens of thousands of years.

CHARAF: Baalbek, as we know from
the archaeological evidence,

must have existed during
the Neolithic Period,

between 6,000 to 8,000 years
or even 9,000 years BC.

NARRATOR: But even
more significant

to ancient astronaut theorists
is their belief

that the colossal stone platform
may once have served

as a landing pad
for space travelers.

CHILDRESS:
We don't know why Baalbek

was chosen
as this specific site.

It may well be some kind
of special power place...

but what was originally there
before the Roman temple

was this spaceport platform
that was apparently used

for extraterrestrials coming
and going on planet Earth.

NARRATOR: As evidence,
researchers point

to the gigantic megalithic
stones incorporated

into the foundation,
each weighing between 800

to 1,200 tons
and perfectly fitted together.

COPPENS: This is the real
mystery of Baalbek...

How these stones
came to be there,

why they were placed there,
and specifically

how they were
transported into place...

Because some of the stones
are of such magnitude

that modern machinery is
incapable of putting them there,

but somehow our ancestors
were able to do this.

TSOUKALOS: Some have suggested
that this stone alone

weighs in excess of 1,200 tons.

How was it moved there?

Because obviously it's situated
on top of these stone rows

that we can find down here,
which means that this stone

had to be lifted and then set on
top of these stones down here.

CHARAF: And because these stones
were gigantic,

ancient people assumed
that extraterrestrial

or unknown forces brought them
to the site itself.

MAN: It is one of the oldest,
oldest megalithic sites

on the planet, and it has
these huge stones laid out

in a precise geometrical shape
at a time

when the prehistoric people
who would have lived there,

who would have gone
to the Beqaa Valley in Lebanon,

would have no concept of how
to move stones of that nature.

NARRATOR: But if the moving,
hoisting, and setting

of such massive stones
was so incredibly difficult,

then who or what
placed them there,

and, perhaps
more importantly, why?

COPPENS: We know
that the ancients

always went to power places, and
Baalbek clearly is one of them.

It is a place where the gods
were worshipped,

where the gods were said
to be present,

and so when it comes to Baalbek,

this platform was built there
for a reason.

For what purpose it was used
is a question we can't answer

at this moment in time,
but what we do know

is that whatever
was happening there

had a great religious
significance to them

and was linked
with worshiping deities,

deities which clearly are
of an otherworldly origin.

NARRATOR: Is it possible,

as ancient astronaut
theorists believe,

that Baalbek had been
considered a sacred place

for tens of thousands of years
because it was where

extraterrestrial beings
first arrived on Earth?

Perhaps the answer can be found
by examining

other megalithic stones
on Easter Island.

NARRATOR:
The South Pacific Ocean.

2,300 miles west
of South America,

in one of the most
remote places on Earth,

giant stone figures stand
with their backs to the sea.

Called moai
by the native inhabitants,

they are the silent sentinels
of Easter Island.

MAN: The moais are scattered
throughout the island,

and they're positioned on top
of platforms, for the most part.

A moai is a stone sculpture
of a deceased ancestor.

They were once
living individuals

who ruled the society
or led the society.

They were chiefs,
and then upon their death,

we believe that they've become
represented in stone.

NARRATOR: Nearly 900 moai
were carved

between the 12th
and 18th centuries.

Hewn with stone tools
from volcanic rock,

the tallest stands
a towering 33 feet high

and weighs a staggering 75 tons.

STEVENSON: They were probably
even more unique-looking

in the past.

They may have been painted,
and they also had

large, white coral eyes
with obsidian pupils.

So it's a very effective way
of kind of telling people

not verbally, but symbolically,
that someone is watching you

and you should toe the line.

You should do what
you're supposed to do.

NARRATOR: The people
who created the moai

called themselves the Rapa Nui,
and mainstream historians

believe their Polynesian
ancestors came to the island

in canoes from across
the vast Pacific Ocean

between 700 and 1100 AD,
but over several centuries,

for reasons
that are still unclear,

what was once an island paradise
withered into a treeless desert

stalked by famine, violence,
and, some say, cannibalism.

When the first Europeans arrived
in 1722, the Rapa Nui culture

had already been
nearly wiped out,

and few could imagine
how such primitive people

could have created the moai.

MAN: How in the heck
did they make these?

Where did they come from,
and how did they move them?

Nobody has the answer.

NARRATOR: Modern scientists have
tried and, so far, have failed

to duplicate the feats
of the ancient Rapa Nui.

In 1987, anthropologist
Charles Love used rollers

to move a nine-ton moai replica

at Western Wyoming
Community College.

Ready? On three.

One, two, three.

Come on. Come on.

Good! Thank you. Whoa.

Only able to budge it
about half an inch.

NARRATOR: Other researchers have
tried pulling moai with sleds,

but there is a unique problem
with the idea

of moving moai
with sleds or rollers.

LOVE: When you go
to Easter Island,

you don't get the impression
they had enough wood

to have rollers, and, in fact,
in the 1700s,

the first four expeditions
to Easter Island

never really saw a tree,

and so that's the real mystery
of Easter Island.

How can you move
a mum-ton statue

if you have no trees
for rollers?

NARRATOR: According to the oral
history of the Rapa Nui,

the moai were moved
in a very unusual way.

LOVE: They all reply
basically the same thing.

The moai walked to the ahu,

and that's the only explanation
that they give.

NARRATOR: But who or what
had the power

to make multi-ton moai appear
to walk to their ahu,

or stone platforms?

In 1919, British archaeologist
Katherine Routledge,

who lived on Easter Island
for a year,

recorded the legends
and testimony of an old woman

who said the moai were moved
with a mystical energy

called mana, and, according
to the oral histories

of the Rapa Nui,
mana came from the gods.

TSOUKALOS: Mana was
a direct gift of the gods

given to the Easter Islanders.

Was this mana really
a type of magical force?

Of course not.

It was some type
of misunderstood technology,

some type of a device,
an extraterrestrial tool

with which you could move those
massive Easter Island heads

rather easily.

NARRATOR: Did early inhabitants
of Easter Island really know

how to unlock the secrets
of gravity using mana,

and, if so, where might
such power

over the physical world
have come from?

Might these astounding
abilities, forever lost to time,

have been made possible
by extraterrestrial visitors?

Perhaps further evidence
can be found

with a mysterious structure
in southern Florida

built from 30-ton coral blocks.

NARRATOR: Homestead, Florida,
30 miles south of Miami.

This former
agricultural town is home

to one of the most mysterious
structures in North America,

a stone garden made
of sculpted blocks

of ancient coral,
some weighing 30 tons.

It's called the Coral Castle.

Spread over several acres,
the complex formations

and intricate designs
of the stone walls

and sculptures marvel tourists,

but unlike other great
structures around the world,

this site is not ancient.

CHILDRESS: Coral Castle
in Florida is often said to be

the only modern megalithic
structure ever built.

NARRATOR: In 1923,
Ed Leedskalnin,

a Latvian immigrant,
began building

what he originally called
Rock Gate Park,

but, believe it or not,
Leedskalnin insisted

that he was not using
modern machinery

to build
the impressive structure.

He also claimed
that he was working alone.

MAN: Well, Ed was a hermit,
and Ed was a loner,

and he was a foreigner, and he
was a recluse and a scientist.

NOORY: He was in love
with a woman,

and he wanted to build
this facility in memory of her,

and he waited for her
to come from Europe,

and he waited, and he waited,
and she never did,

but the big question is,
how did this frail, little man

move these thousands of pounds
of block by himself.

NARRATOR: Barely over
five feet tall

and weighing just 100 pounds,
Leedskalnin is said

to have carved, moved,
and hoisted

huge multi-ton stones
using only a makeshift tripod.

McCLURE: He has a tripod,
three pieces of Florida pine,

and he's got some chains,
and he's now gonna lift

30 tons, ten tons of rock?

Can't be done.
No one could do that.

NOORY: He would work at night.

He wouldn't let anybody
watch him,

and he said that he knew
the secrets of the pyramids.

NARRATOR: But what, exactly,
was Leedskalnin referring to?

Had he rediscovered
the same advanced technology

used to build
megalithic structures

like Carnac and Gobekli Tepe?

McCLURE: Ed over and over again
would tell people that he knew

the secrets that helped the
Egyptians build the pyramids.

What was he talking about?

Why was he constantly
harking back to the Egyptians?

We don't know.

NARRATOR: Leedskalnin continued
work on the Coral Castle

until his death in 1951.

In the journals he left behind,
the builder explained

that he had discovered
the ancient secret

of transforming stones
into weightless objects.

McCLURE: Ed says this in
his pamphlet "Magnetic Current,"

that real gravity
is actually real magnet.

So if you reverse
the magnet forces with a force

of some kind of electromagnetic
radio, perhaps, frequency,

you can then make
these rocks not as heavy

as they seem otherwise, and,
therefore, you can lift them.

NARRATOR: But if Leedskalnin
had developed a device

that could modify gravity,
what was his secret?

Some suggest the answer lies
in a mysterious black box

that can be seen
in various photographs,

a box that has since
disappeared.

McCLURE: The black box sitting
on top is the element

that no one has ever seen
except in those pictures

and no one has today.

We believe that black box
has something to do

with how he got these massive,
heavy, brittle pieces of rock

up in the air in a way
that no one can duplicate.

NOORY: He had some kind
of magnetic machine

down in one
of his other house areas

that has since been dismantled,
but it had a revolving ability.

He may have been having
that thing spin.

The whole place
could have been antigravity.

He probably just pushed
these into place.

WOMAN: Levitation
is the only way that I know of

to hold up very heavy objects.

Very, very high-speed trains
are magnetically levitated.

These high-speed trains

don't have wheels
that touch any tracks.

They're literally
suspended above the track

using magnetic forces.

MAN: We can speculate at this
time that there are techniques

for using electromagnetism
to nullify gravity.

This was the great quest
of Einstein.

The motivation for such
technology is, of course,

to lift a large spaceship
out into space and across space.

MAN: Oh, all right. Ha ha ha!

NARRATOR: Could it be
that Ed Leedskalnin

utilized antigravity to levitate
and distribute

the enormous rocks used to build
Coral Castle?

If so, where did this
incredible knowledge come from?

COPPENS: And he died,
taking this secret to his grave.

The question is,
did he invent it,

or did he himself somehow
inherit it or learn it

from a tradition or maybe from
some visitor from another realm?

McCLURE: The only thing that
is explainable is that someone

with a higher form of physics
and understanding of gravity

has created the ability
of one person to lift stones

that modern technology
could not do the way he did it.

It had to come from a different
place in this galaxy.

TSOUKALOS: The fact that one guy
created these massive structures

is absolutely fascinating.

Am I suggesting that he did this

with extraterrestrial
technology?

No, because I don't know.

Am I excluding that possibility?
No.

NARRATOR: If aliens visited
Earth in ancient times,

perhaps the world's
mysterious stone structures

can provide clues not only
to mankind's past,

but to its future.

VON DANIKEN: I think
that extraterrestrials

would not have left
our solar system

some thousands of years ago
without any proof.

They wanted that
in the far future,

we start to reflect, "Have we
been visited by outer space?"

NARRATOR:
Could additional evidence

still lie hidden
right before our eyes,

evidence that, when found,

will prove once and for all
that we are not alone?
