By analogy, I gather there is controversy regarding whether upper, middle and lower ancient Egypt each had their own pharoah, running concurrently, overlapping unenvenly and occasionally transitioning to a unified Egypt, under a single Pharoah, later splitting again and generally pickling any attempt by an outsider, in Bishop Usher's time period to piece it all together again from fragmented written records, bearing only regnal date symptoms.
I cannot remember whether this threatens to telescope the notorious 6000 years of earth's existence to an even shorter period or if it lengthens it, after all the errors are sorted out.
