Viewing human civilisation as less than ten thousand years old fits so well with archaeology of major civilised administrative centres like Eridu, Uruk, Ur and Susa. The pyramids and famous architectural achievements of human civilisation all date to less than ten thousand years ago. Nothing major of indisputable human homo sapiens making date from older periods. Even the exceptions are so hard to pinpoint with certainty that they prove the rule. It is consistent with documented contemporary historical records that the human at the beginning of this whole timespan had no earthly parents but originated with the gods.
