I grant that you have not claimed that the planet is only a few thousand years old, but you appear to be saying here that there are significant errors in the ages obtained for rocks. How large do you think these errors are? Do you think, for example, that the age of the beginning of the Cambrian period was only 500 million years rather than the generally accepted age of 542 million years, or do you think that the true age was only about 5 million years? How large, in your opinion, do the errors in age have to be to vitiate the fossil record as evidence for evolution?
If you google on 'geological time scale' you will obtain about 121 million results; the different versions of the time scale for the Phanerozoic eon are by now in agreement to within better than 1%. What evidence have you that the errors in the time scale are large enough to cast doubt on the fossil record of the evolution of living things, and, in particular, on the evolution of Homo from the australopithecines and, before them, from Miocene apes?
