I have studied the Vedas for many years - and there is a lot of evidence of the vast antiquity of human civilization. Also story of an ancient flood. And that human civilization was spread more all over the world - and thus similarities can be noted, although modern archeologists do a lot of cover ups since they are all true believers in the current evolutionary-humans-were-hunter-gatherers a few thousand years ago. To think that modern civilization may not be the apex of human endeavor is blasphemy for such people and so they do not like evidence that shows otherwise.
There is a cool video hosted by Charlton Heston - I can't remember the name and I have it! It described and shows various anomolous evidence, positing that human existence on the planet is probably way way older than the "catechism" we've been indoctrinated to believe.
