I continue to be amazed at the blindness of these life-by-incremental-changes folk. Found within THIS set of rock strata or with THESE fossils = 47,000,000 years old, never mind that we found organic material still organic, still intact with it. More willing to say organic material won't decompose over 47,000,000 years than willing to say our dating methods need re-thinking.
Couldn't possibly be 47,000 years, oh no, not at all. 4,700 years? Don't be thilly!
