In fact, I've seen some that go eight, 9,000 years ago. Now one misconception, significant misconception, about the Americas is that when the Europeans colonized, remember Columbus sailing in 1492 looking for the East Indies, and then he bumps into this, he actually doesn't bump into the whole continent, he bumps into an island that's close to the continent. But with that, you start having the beginning of the European colonization of the Americas, roughly the last 500 years. And one misconception that folks often have is, well, it was maybe sparsely populated, mainly by hunter-gatherer nomadic people, and nothing could be further from the truth. The modern estimates of the population of the Americas at the time of the European colonization, roughly around 1500, is one is 50 to 100 million people. And to put that in perspective, so that's right around there, that's about 10 to 20% of the world population at that time. The world population at that time was about 500 million people.
