Why did Egyptians use Kemet?
A number of names were used for Egypt. A popular ancient name for Egypt was “Kemet,” which means the “black land.” Scholars generally believe that this name derived from the fertile soil that was left over when the Nile flood receded in August.

The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture.
