The first humans depended so much on the weather, the environment, food, and shelter to survive. They used to be nomads, gather-hunters, that followed animal herds to hunt them and feed their families. During the Neolithic Revolution, humans started to learn agriculture techniques that allowed them to settle in one place and grow crops and later, founding towns and cities. That was the case -for instance- of the Sumerians, the ancient human civilization. They settled between the Tigres and Euphrates Rivers in what today is Iraq and founded many city-states such as Uruk, Ur, and Lagash.
