In one way, we can say that humans started to settle when they learned agriculture and developed agriculture techniques.
Let's have in mind that ancient humans were nomads. Yes, they followed animal herds to hunt them and feed their families. However, as soon as they started to grow crops, they could settle in one place as was the case of the oldest civilization of Earth: the Sumerians.
The Sumerians settled in the middle of the Tigris and Euphrates Rivers in the Middle East region, modern-day Iraq. There, they founded powerful city-states such as Nippur, Eridu, Kish, Ur, Uruk, and Lagash.
