they migrated mostly over land from Africa over the last eighty thousand years.

This fits the current scientific consensus: anatomically modern humans originated in Africa and began spreading out (mainly via land routes) around 60–80 thousand years ago, with later coastal/short-sea crossings for places like Australia and eventual entry to the Americas via the Bering land bridge.
