The ancient Egyptians called their homeland KEMET, or the "black land" distinguishing it from the desert that surrounded it, which they called DESHRET, meaning the "red land".
They referred to themselves as REMET-EN-KEMET,(the people of the black land).
The black land was arable earth, the fartile silt that the Nile deposited each year when it overflowed its banks, and that black land covered the same extent as the Nile's annual floods.
During the Tertiary Period (around 45 milion years ago) Egypt was entirely covered by the great ocean Tethys.
When, towards the end of the Tertiary Period, the great mountain-building movements of the earth's continental plates led to the formation of the Himalayas and the Alps, the waters of the massive ancient sea dropped, the basin of the Mediterranean Sea was formed, and the territories now called Egypt and the Sahara emerged.
