There could have been talking trees and stationary dinasaurs and Winnie The Poohs everywhere for all any of US know.

I don't know that it matters a great deal to anything we have to make crucial decisions about whether the beginning of Adam was 6,000 or 60,000 years ago. I'm inclined to think it was likely significantly longer ago than 6,000 years as we know them. But then if light has been slowing down--all kinds of standards don't look quite as rigid as we've tended to construe them.
Just my 2NT$ worth.
