Crash? You're throwing me here. You don't listen to Rush Limbaugh, do you?
Uh, lord no. (I sure did, though, once. Legacy of a mis-spent childhood.
)
It's possible we had villages in South America 60,000 years ago, and it's certain we had them there 20,000 years ago. Why don't those people count?
They don't count because I'm a crappy historian.
By which I mean to say that I picked a number off the top of my head that sounded reasonable. Obviously I was way off.
So, 20,000 years, or even 200,000. Still way less than the dinosaurs.
