The population count was probably much higher than current estimates. If the count was as estimated, we would have died out.

At 1,000 BC the global population estimate is ~50 Million. Don't know what that number would back down to in 3,000 BC, assuming everything else was equal, which it never is...

I was measuring population "then" against population "now". All past times have dramatically smaller populations than today.
