Have a look at the ages of some of the early legendary Chinese rulers. The Heavenly Sovereign (天皇) ruled for 18,000 years, but he was a demigod rather than pure human. His second successor, the Human Sovereign (人皇) founded a dynasty that lasted for 150 generations and spanned 45,000 years.There is a lineage from Adam. That would lead me to believe that believe that this is more modern, rather than ancient. I am not aware of an oral tradition going back tens of thousands of years.
Ancient peoples had no problems with ascribing long lifetimes to important ancestors.
