The Sahara Desert used to be a lush forest, thousands of years ago, where lots of people lived. Then it dried up through temperature changes of just a couple degrees. It took about 150 years or so, a geological blink of the eye. But long enough for some of the people to move, probably to Egypt.

Of course, then people started grazing goats in the grasslands and scrublands around the desert, and goats ever bloody everything, which only made the desert bigger.
