Human beings have been around, in their current state of intellectual capacity for well over 100,000 years.

Looking at all that we’ve accomplished in just the last 10,000 years of known history…it is not unreasonable to assume that we could have accomplished just as much several times over already…but for whatever reason the knowledge of those accomplishments have been repeatedly erased from history.

I’m gonna piggy back mine on this one. Before the invention of writing, the only new thoughts you could ever encounter, were from the people you would meet face to face.
