hunter-gatherers 2 million years ago? Nope.

We have not found ANY evidence that man Man was around until around 5000 to 7000 years ago. Pyramids, working with metal, languages, it all happened very, very quickly.
Man started building incredible structures all around the world and started writing things down and figured out a great deal about the heavens including very accurate calendars and maps of stars.
Coincidence? No.
There is an incredible amount of evidence that man existed then and ever since then, but there is no evidence of man's existance prior to that time except for some ape-like skeletons they found.

Mankind as we know it has only been around for a short time. There may have been some man-like creatures before, but they were not man as we know today.
