Experiments to move massive megaliths with ancient technology failed miserably to replicate what lost civilizations did hundreds of years ago! Philip Corso claims he shared alien technology with corporations sixty to seventy years ago, if true it could explain rapid development of modern technology, and possibly how ancient megaliths were moved! If they are covering this up, then a large portion of our history is based on lies, combined with political insanity, which might explain Trump's clownish and phony posturing, although it also leads to more questions!
