This has nothing to do with politics. The News and Observer reports (10-25-06) two scientists have determined millions of years ago the Amazon River flowed in the opposite direction.

I know it’s akin to heresy to question anything scientific but, sometimes, it’s hard not to wonder about scientists. How can they be so certain what happened a hundred million years ago? They say they proved the fact by testing alluvial mud. But you have to wonder, couldn’t there be a dozen or a hundred or a thousand explanations for the minerals in that sediment they’ve never dreamed of?

I guess one thing’s for sure: when scientist says with certainty he knows what happened a hundred million years ago, it’s going to be tough to prove he’s wrong.
