And we also know that these people are not the same people that are living there today. They're not Indians. They're not Pakistanians in terms of their heritage and where they came from. Most likely, they came from the Caucasus areas that are north of all of those mountains we talked about. There's evidence as far back as 7000 BCE, which is like the beginning of the Neolithic era, right? That they were extracting their teeth and filling cavities, that they were domesticating animals and growing food. But for whatever reason, these northern people came through the passes that the mountains gave them into this valley, and they figured out quite quickly that this was the place that you want to settle because the land is just so fertile.
