As I said to Mark, there is a lot I could say about this subject. I'm being cautious at present, because I don't know how comfortable I am getting into this online in a public forum. It is far too easy to sound insane when talking about this stuff. But you are quite right when you point to folklore and the alarming similarity in stories from ancient cultures across the world, regarding this subject.

From a purely Christian perspective, I believe there is a massive deception coming upon the world regarding the true nature of the UFO/alien phenomenon. It isn't benevolent, and I believe the Bible warns about what's coming. But again, that's a discussion I don't feel comfortable having online. Yet.
