The oldest documented human civilization was near the confluence of the Tigris and Euphrates rivers about 10,000 years ago. Going beyond that brings us into the realm of the "Man or monkey" arguments and right back to the debate over creation or evolution. Jumping from 10,000 years to 200,000 years without archaeological proof is too much of a jump to be believed.
Of course there's the just as provable "aliens transplanted on Earth" theory
