Alright guys, why don't we start with geography one on one so you know on earth where we're talking about. And if we're talking about the Indus River Valley civilization, you probably want to know where the Indus River is. Not only the Indus River, but you also have the Ganges River and all of the tributaries that flow from the northern mountains into the Arabian Sea. So the area of the world is today the border between India and Pakistan. You should know from the map that India is kind of the belly of the east. If you go to the northeast, you're going to run into China. And if you go to the west of India through Pakistan, you're in Iran, the gateway to the Middle East.
