These so called professional alien historians and researchers are nuts. They still insist on aliens coming down and either using anti grav rods or giving the cultures like the mayans or whoever the rods to make it easier to build the temples and pyramids.

Bullcrap.

Here's the thing about the drawings inside the pyramdis and temples. Has it ever occurred to you that they built a wall first and then did the drawings and moved on to the next few walls? Doing this in broad daylight that's how they did the drawings in good shape. Then when they got done with the drawings the built the rest of the temple or pyramid. It's the simple.

Damn ancient culture historians are the types of people that paint themselves in a corner when trying to paint a room

Hi urrutiap, I've watched several ancient egypt and alien/UFO documentaries that appeared on Discovery and History channels.
I don't get the point you're trying to make. Could you please elaborate?

I also think that History and Discovery make some shows just to make money. Focusing on a wider viewer demographic so they can appeal to "anyone".
But this is just my 2 cents.
