Watched Ancient Aliens on the History Channel today.
Really interesting stuff on Ancient Egypt and Extra terrestrial influence.
The Theory on The Great Pyramid is astonishing. Basically, the theory states that ancient astronauts had humans build this Pyramid with two tunnels on each side. They would combine elements through each tunnel to create hydrogen and conjure energy.
I don't know about all this but the theories about gods or "celestial beings" actually being Ancient astronauts (Aliens) was pretty convincing and rational.
Check it out!
Also The States is a pretty good show as well.
