Ago History began when humans learned to read and write. The first writing we know of came from civilizations in Mesopotamia and Egypt about 5500 years ago. People lived for thousands of years before this, but little changed from generation to generation. People lived as nomads.
Nomads are people who have no permanent home.
Men hunted animals and women gathered wild plants. When there were no more animals to hunt or plants to gather, they moved to a new place. Society developed when people began to do individual jobs. When people do only one job, they usually choose a job they enjoy and do well. Further, when you do the same job over and over, you learn to do it very well.
