I'll be right back. I think for the last, look at the river, amazing. I think for the last like a thousand years, the first question on the regions is something to do with water. Water is humongous in terms of early development of civilizations. So river valleys, and not just rivers, but river valleys, where the river kind of flows low and usually into a larger body of water is generally where we find the Neolithic world development. Remember, the Paleolithic world is more of, or the Old Stone Age, is more of people really being nomadic and kind of wandering around, still based on geography, but more about kind of weather and the scarcity of food supply, chasing the buffalo or the Ice Age, those kinds of concepts. And as the Ice Age comes to an end, you know, people differ about this when the Neolithic Age started, but I would guess anywhere from 30,000 years ago to 10,000 years ago, you start having people chilling, you know, where they're going to discover that near these early, you know, these river valleys that they don't have to keep traveling because they have the ability, because of the geography, to grow food.
