The interesting part is that the brits calculations on the age of the earth roughly correlate with the Jewish calendar which begins in 3761 BC.

The Jewish calendar system is not biblical but rather comes from extra biblical sources—like the sumerians— whose beginnings archaelogist estimate to have started sometime after 4000 BC. They lasted until about 2000 BC when they were defeated by Hammmurabi’s babylonians. Hammurabi like his successors simply grafted the Sumerian civilization achievements like mathematic, writing and literature onto their own civilizations.
The the sumerians were to their successors in the region like the Greeks were to the Romans.
Parts of Sumerian myth and history have their echos in genesis.
The patriarch Abraham left one of the capitals of Sumeria—Ur—At the time of the final crack up of the sumerian civilization.
Oh I’m hip to the history, just good to see someone else who understands the historical chain of facts rather than just dreamed up stuff.
