What does contemporary mean in this context? i.e. what's not considered 'contemporary'
We consider Adam, Noah ancient. But the Romans? Might as well have been last week.
Even Moses, who might have lived around the 13th century bc would have been 1000 years after Sargon of Akkad.
There is a lot of history to go around, so many peoples and civilisations that we know of, and so many that we do not.
