I love ancient alien we recently went to an ancient mysteries conference at the Edgar Cayce center and we met Giorgio in fact I took a picture of my husband and Giorgio tsouk He was a very nice and straight forward kind of guy. We listened to a talk by David Hatcher Childress it was a great time. I don't know what really happened on this planet in the past the archeological evidence is very interesting and it begs many questions. There's many mysteries the puma punku ruins, ollantaytambo the windover bog people in Florida. What I do believe is that we've been enslaved by biblical fantasies of magical angels and a capricious god demanding our allegiance or else.
Certainly the idea that a more advanced technological race visiting our planet in the past is not absurd and crazy in comparison. I don't know the answers I wish I did but for me the alien possibility is still open.
