- btw to your earth age problem: I don't know the history of the earth age determination, but suppose that an estimate based on sedimentation speed was used before we had radiometric dating. This way a lower boundary of the earth age could be estimated, like several hundred million years. Maybe you were confusing the lower boundary with the real age?
