August 2015.
A sinkhole is discovered
under the 1,000-year-old El Castillo temple.
Scientists, worried about the stability of the pyramid,
begin extensive examinations of the site.
[dramatic music plays]
While investigating,
they discovered two nested structures
contained within the confines of the pyramid.
[man]
is actually not one pyramid, but three.
These are built like Russian dolls.
They keep repeating the same design feature,
the same construction method,
the same unit of measure over time.
So obviously something worked thousands of years ago
and they kept repeating it again and again and again
like a cookie cutter process.
It is a pyramid that's inside of another pyramid.
We also see this
at the Great Pyramid of Cholula,
one of the largest pyramids in the world,
just outside of Mexico City.
Also, we see this
at Djoser's pyramid in Saqqara in Egypt.
So ancient peoples were, for some reason,
rebuilding over and over again
these ancient structures.
Did the extraterrestrials who had designed these temples
have a certain purpose in mind?
Something that we still don't understand?
[music slowly intensifies, then drops off suddenly]
[narrator]
and rebuilding of these nested structures,
as ancient astronaut theorists propose,
does it suggest that, over time,
there may have been a need for larger architecture?
If so, could it be
that they served a technological function?
And much like the ancient constructions
that fall within the ley lines of Europe,
might the sacred sites found worldwide
also connect to a larger blueprint?
The origins of the idea of a world grid
can be traced back to Ancient Greece.
Philosophers like Plato were very adamant
that the ancient sacred places
were specially positioned along the face of the Earth
in a very deliberate way,
and they conformed to what's called a world grid.
The temples were not placed haphazardly.
They actually had a structure and purpose to them.

[narrator]
researcher Ivan T. Sanderson
plotted out his own planetary grid
based on Plato's work.
Other world grid researchers
would later build upon his model.
What they identified was that there was a geometric pattern
that could be superimposed on the Earth
and that grid point usually started
at the Great Pyramid itself,
and they would go out from there in a geometric form.
[man]
of all of the large stone structures
that have ever been found all over the Earth.
A total of 3,300 different stone structures.
And they found that every single one of them
was built right on
one of the lines of this geometric pattern.
On this grid, sites like Stonehenge in England,
megaliths in West Africa,
the Bermuda Triangle,
pyramids in Mexico and in Peru,
islands like Easter Island,
the bizarre city of Nan Madol,
were also matching this grid.
The specific power spots
where we find pyramids and obelisks and other structures
may have not been chosen just by chance.
It could well be that they are part of an integrated hull
and their location is highly, highly important.
Some researchers speculate
that ancient cultures around the world
connected all of their temples to each other
almost like a master circuit board.
Where one temple connected to another temple
connected to another added to the power
of the structure,
added to the power of the line itself.
