I think the number is 600,000 years for how long we've been around in total.

I completely agree with you. If you actually think about it seriously our history as a species is amazing. Things like the discovery channel with the "Aliens" guy piss me off. It's a fundamental disrespect of what real people have done, and what we're capable of.

The long ramp up to what we have right now today is fascinating. No other animal has ever done anything like we have. From loin clothes to fire to farming is mind blowing. Hell, just one of those things is already way past every other species to ever live.
