Over 3,000 yrs. ago, the ancient Egyptians called one strip of their country the Black Land. It was made arable by a yearly gift of rich silt from the Nile River. At its edge was the dry Red Land, the inhospitable desert. The people who lived along the Nile had no name for their river. The waters provided their sustenance, their communication, their transportation. The Nile figured so prominently as their main street that they had no use for horses and carts for centuries~Wiki.
