I have been watching the History Channel, and they are doing segments on these structures, and their relationship to ancient astronauts and the gods from antiquity. HC is also doing repetitive segments on aliens and UFOs. Why is it that a channel dedicated to history, would air such topic matter, if it weren't trying to tell us something, to possibly prepare us for something out of the ordinary? Are the folks in public broadcasting and Hollywood reaching out to us? When I watched the segment on Puma Punku, the scientist stated that it was more of a spectacular monument as a feat in engineering than the great Pyramid Of Giza. A feat of the gods, just 40 years ago as a 7 year old I read a book named "Chariots Of The Gods" by Erik Von Daniken. I believed his findings then, and now. He is on the History Channel quite a bit, and to think he was beaten within an inch of his life all those years ago by religious fanatics, the man endured such criticism its aa wonder how he held on all these decades. But he did, and now he shines on as an expert in the field of study, ancient astronauts and their monumental structures.
