first settlements in the Nile Valley began around 7,000 years ago.
Hunters and gatherers moved to the Nile Valley from less fertile areas

settlements gradually developed into more and more complex societies. Most Egyptians lived near the Nile as it provided water, food, transportation and excellent, fertile soil
