egypt and nubia
Sub-Saharan civilization which took place in ancient Egypt, Swahili and Nubia were the names of the civilizations in Africa.
The river in Nubia is different from the one in Egypt because the Nile River in Nubia is not to smooth as the Nile River in Egypt.
They were probably the same because they worship the same god. They had leader who rule their land. Their practice were the same, since they both did mummification. They both build pyramid, but Ancient Egypt pyramid doesn't have a flat top like Nubia.

The three early river civilizations are the Incas. Aztecs and Mayas
the nile river
EGYPT.
Because the Nile River did not flood in Nubia as much as it did in Egypt
