I think they give just about anybody a shot at coming up with some sort of far-fetched "what if" story - then throw it out on the air to see if any of it sticks. None of it can be proven. It's ALL way out there. But it does provoke some thoughts just simply about: How did they move that big heavy shit back then? How did they cut those stones that well? Why DO some of those drawings look the way they do? Intriguing questions - and way far out there theories about how and who did it all. Kind of like our "climate experts"… these folks are being paid to come up with this stuff.
How do I get on that "what if" gravy train?
