@sunmaster,
you made a comment about "information that has been passed down thousands of years".
well, you would have to assume that the information was kept in tact for those thousands of years.
never corrupted or modified or tainted in any way.
passing through thousands of hands throughout those thousands of years.
your comment reminded me of a quote attributed to buddha.
"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense."
