For some reason I am reminded of the story of the man in the flood who prays for God to help him, but rejects the man in the truck, the man in the boat, and the man in the helicopter, only to accuse God of not helping him when he arrives, inevitably, before Him. "But," says God, "I sent you a truck, a boat and a helicopter."

So stratigraphy, ice cores, dendrochronology, isotopic dating, fossil sequences, DNA similarities et al, are not evidence, as the men in the story were not help.
