Actually I first read of this theory some 36 years ago in the book "Chariots of the Gods" by Erich Von Daniken. This predates "Coast-to-coast" by quite a bit.
But I'm not about to debate Evolution/Creation/Aliens with you because it's a no-win argument and I really don't care.
However I do think that it's interesting the many very curious things on this planet that have never been explained- either by science or religion.
