Explanation:

The Nile is a river in Africa, and is generally regarded as the world's longest river, although some claim that the Amazon is longer.

The Nile often floods over its shores in the lowlands, making the banks a very fertile territory, which was already exploited in ancient Egypt. They sowed grain there, and when it rained, the sides were fertilized and it grew faster than usual. Most of Egypt's population, and all of Egypt's cities except those close to the coast, are located on the Nile north of Aswan, and almost all cultural and historical sites of ancient Egypt are on the banks of the Nile River. From Lake Victoria, the Nile flows through Uganda, South Sudan, Sudan and Egypt before spreading into the Nile Delta and ending in the Mediterranean.
