And that's a very important feature, having access to water in that part of the world. You're also surrounded by mountains. It's nice to have mountains when you don't want to be invaded and such. So you have the Himalayan mountains to the north, you have the Hindu Kush mountains to the north, and you have the Karakoram mountains to the north, which is going to give you a very good wall of defense. And I even have some more good news, kids. You have the Arabian Sea. All of these rivers flow into the Arabian Sea, which is going to give the Indus River Valley Civilization access to that water, and eventually access to the Persian Gulf, which is access to Mesopotamia.
