Ancient Aliens

This wall exists here,

at one of the most inaccessible places.

These types of walls, they exist all over the world.

The building style is not similar, it is identical.

Were alien structures built on Earth

as part of a master plan?

That these temples actually act as batteries.

They store energy and they also allow the energy to expand

at certain times during the day.

Could they reveal an extraterrestrial connection?

Ancient cultures around the world

connected their temples to each other

almost like a master circuit board.

And did they serve a larger purpose,

one that reaches beyond Earth?

They're somehow looking at the Earth from space

and seeing how these structures would fit around the globe.

Who could be doing this, except for extraterrestrials?

Siem Reap, Northwest Cambodia.

Just outside the magnificent ruins of Angkor Wat

stands an ancient pyramid temple known as Baksei Chamkrong.

While it is a solid rock structure,

and therefore cannot be carbon dated,

mainstream archaeologists suggest

that it was constructed in the tenth century AD.

9,000 miles away, in the Petén Basin of Guatemala,

lay the ruins of the Mayan city of Tikal.

Amongst the long-abandoned structures

is a Temple of the Great Jaguar,

which is believed to date back to the eighth century AD.

When you see pictures of these two pyramids

on two different continents, they're virtually identical.

It's as if the same architect had designed both of these.

Although the Cambodian pyramid

is much smaller than the pyramid in Guatemala,

the similarities between the specific design features

are uncanny.

Both have an unusually steep slope angle

that we don't see in other pyramids,

they both have a stepped formation.

There's a stairwell going up the middle,

there's a domed area on the top,

there's a little door that goes in

and there's interior structure that looks the same, as well.

You have the civilization in Cambodia

and the civilization in Mesoamerica.

There are so many parallels, it's incredible.

It's unbelievable that scholars haven't, until now,

recognized those parallels.

Is it possible that they were working off the same blueprint?

And if so, where did that blueprint come from?

Could it be that these seemingly unrelated sites,

located thousands of miles apart,

share a common architect?

Cambodian lore attributes the building of Angkor

to Preah Pisnokar,

a being of half-human, half-divine origin.

Preah Pisnokar is the son of the moon goddess and a mortal.

One day, she takes him up to Heaven,

where he meets the great high god Indra,

who decides that the boy is to be given special schooling.

At Indra's Heaven, he was given instructions.

Instructions about mathematics, engineering, architecture,

all these different scientific disciplines.

One very provocative way of looking at this story

is that Indra's Heaven is not just a place in the stars,

that it's actually a spacecraft.

And that Preah Pisnokar was instructed

by extraterrestrial beings on this craft

in the art of temple making.

According to ancient astronaut theorists,

an interesting parallel exists

between the Mayan and Cambodian stories.

In the Maya manuscripts,

the god Kukulkan is responsible for their temple architecture.

He was also credited with educating humans

on mathematics, engineering and science,

the same teachings attributed to Pisnokar.

Kukulkan is supposed to have descended

from a star.

He's represented as the feathered serpent,

but also he's represented,

he's a big being with the helmet,

a helmet has rays on it,

and he's sitting on a half-open sort of egg.

He was the teacher, according to Central American mythology.

He definitely is an extraterrestrial.

Could these two otherworldly architects

be one and the same?

And if so, does further evidence of a master builder exist

in other parts of the world as well?

In Mesoamerica,

we have the gods associated with the construction

of the pyramids over there.

This reflects the same kind of entity

that the Mesopotamians reported,

that the Egyptians reported as being the architect

that designed the cities, that designed these structures.

So you have the same pattern and the same claim

happening over and over again

over a span of at least 7,000 years,

where it's the same type of god,

planning and directing the construction

of these types of similar buildings.

We seem to be talking about the same architect

that seems to be crossing

different continents at different times.

It's interesting that when you start

looking at all of these structures

covering many thousands of years,

you begin to see that there's a relationship.

Pyramids are found by the hundreds

in nearly every region of the world,

including Central America, Mesopotamia, Egypt,

China and even Antarctica.

And many cultures' most sacred structures

appear remarkably alike.

It is striking that you can travel around the planet

and you can find structures that are similar in nature.

For example, in China, the Xi'an Altar of Heaven,

or the stone circle above Saksaywaman in Peru.

All over the planet,

you see tall, megalithic architecture.

You see cyclopean stone structures, as well.

A bunch of primitive people somehow get motivated

all over the world to haul around

these gigantic blocks of stone that could be 20 tons, 100 tons.

And everybody around the world

seemed to be doing the same thing.

There is a kind of a master blueprint

that we see in the architecture,

and it's not in just one or two or three civilizations,

it's in all the civilizations.

China, India, South America, it's there.

Archeologists tell us, "Well,

there was no connection at those times."

There had to be something,

that's too much of a coincidence.

So there we get the idea that it's more of a network

than any single structure.

And they sort of feed of ch other.

Are the curious parallels between structures

seen throughout the world truly random,

or could they be interconnected?

And if so, was it important

not just that the temples were built,

but exactly how they were constructed?

Cusco, Peru.

The remnants of the Coricancha, or Temple of the Sun,

are considered a marvel of Incan architecture.

Modern engineers say the precision of the stonework

rivals that being produced today with advanced machining.

But incredibly, the Inca weren't the only ancient people

to achieve such building proficiency.

6,500 miles away in Giza, Egypt,

we see the same signature building techniques

at the Valley Temple next to the Sphinx.

Let's say you stand in front of the Sphinx temple in Egypt

and you look at the stone masonry there.

And then you had the capability of closing your eyes

and the next moment you're at the Coricancha temple in Cusco.

Well, if you wouldn't know where you are,

you couldn't tell the difference between the two,

because the engineering styles of those two temples

are very similar.

What you find is that the blocks

are fitted together so tightly...

What makes these structures so impressive

is not only their design, but also the fact

that they were built with megalithic stones.

Some of these massive blocks are so large

that even engineers today

have no idea how they were put in place.

The limestone blocks at the Valley Temple

are estimated to weigh upwards of 200 tons each.

And many of these stones had to be lifted and placed

up to 40 feet aboveground,

or the height of a four-story building.

However, this was not merely accomplished at these two sites.

Across the globe, ancient cultures chose,

time and time again,

to build with similar awe-inspiring blocks

fitted together with minimal clearance

between adjacent stones and no use of mortar.

Even more confounding

is the fact that many of these megalithic constructions

were built in impractical locations,

often thousands of feet above sea level.

Santorini, Greece.

Researcher and editor Giorgio Tsoukalos

traveled to the ancient site of Thera

on the island's highest peak.

The megalithic architecture found here

dates back to at least the ninth century BC.

This wall exists here,

at one of the most inaccessible places.

In order to get here, you take a car,

you go up these harrowing switchback roads

and then, you're on foot for at least 45 minutes.

And so the idea that is given
