There's certainly some interesting theories, John. Trouble is, finding any sort of evidence to back it up. Until then, all the theories have exactly the same validity as my theory that Neptune is actually made of Christmas pudding and Pluto is a giant glob of brandy butter to go with it. They are no more valid than that. :-)

I don't mean this as derision, merely to show how tenuous these theories are, and how little there is to back them up. Actually, a more accurate work would be "hypotheses" - there generally isn't enough evidence backing them to call them "theories".

Von Daniken provided little or no proof for Chariots of the Gods. I read the book, and what comes across is the wild-eyed theorising - the book is one big brain-storming session, VD asking "what if". It has no basis as a factual document.
