I think for me, one of the most interesting of the sites is definitely Puma Punku, dating officially to 5,000 years old, but more are saying it's closer to 17,000. Evidence abounds of use for modern machining including lazers or saws? A construction feet that most modern engineers wouldn't even consider attempting. Not, that they CAN'T do it,just most wouldn't even want to try.
So, taking a critical look at Puma Punku, and many others through out the world. Did our ancient ancestors have Extraterrestrial help?
