The Great Pyramid at Giza is a power plant.

We would know that, accept for all the "Bendy Truths" they teach people in "science class".

Did you know that other pyramids around the world have encoded in their shape, size and placement exactly where the Great Pyramid at Giza is?

Did the science classes teach you that granite is a semi-conductor?
This used to be common knowledge, as electrical engineers went out rock hunting with electrical fingers to find naturally occurring diodes and transistors. Now that we can make them from doped silicone, we have forgotten about these old days.

Of course there are tons of signs that someone with much more mechanical and machining know how was here on earth. Could be humans, could be aliens, could be gods for all we know. There are a lot of things that shouldn't exist. Man currently has just enough engineering know how to tell just how much engineering is missing between what we can do today and what was done over 5000 years ago.

Fortunately things like the electric universe model are gaining more traction, and so the "settled science" is being questioned.

And, antarctica is about to break out into the main stream. Where we will be shown pyramids that make the great one at Giza look small and dinky. Where we will see ancient technologies that will rock our world. And hopefully we will learn a lot about the path of man through time.
