How was the nile isolated

Ancient Egyptians lived throughout the Nile River valley and delta, shielded on all sides by deserts, seas, mountains and rapids. To the east, a small desert separates the river valley from the Red Sea, while the Sahara Desert lies to the west, stretching almost all the way across the continent. To the north, the Mediterranean Sea separated the Egyptians from European people, while mountains and rushing rapids protected the south.
