the nile river

The Nile river is the longest river in the world, it is approximately 4,000 miles from East Africa to the Mediterranean. Studies have shown that the River gradually changed its location and size over millions of years. The Nile flows from the mountains in the south to the Mediterranean in the north. Egyptians traveling to other lands would comment on the "wrong" flow of other rivers. For example, a text of I in Nubia describes the great Euphrates river as the "inverted water that goes downstream in going upstream."
