A few years back, I heard about this and have recently seen a show and found several more articles on this. I LOVE that the idea that human civilization is WAY older than was previously thought is now being seriously considered! My own feelings etc. about Atlantis seems more and more valid. They did NOT come from space, have lasers etc. But they were building cities and had culture and civilization when most of the world was primitive and living in caves!
Anyway, very thought provoking and cool!
