I oversimplify, of course. There are many alternative theories explaining our origins but I will not cover them here. This article focuses of prehistory — a period of time dating back to approximately 200 000 y.b.p and lasting till 5000 y.b.p, or more significantly, when the Sapiens first roamed the Earth.
