Ancient Egypt Starting about 8,000BC, all of Northern Africa became a drier, more desert-like place. Back then, man lived in nomadic groups of hunters and gatherer. The climate forced man to migrate to more hospitable lands, some migrated to Nile River Valley which is a vast land surrounding the Nile River. There in this land abundant with life, there were plenty of food and water for these people. During the Neolithic Revolution (10,000BC to 3,500BC) man discovered the art of agriculture, this skill arrived in Egypt approximately 7,000BC. Humans were finally able to use the rich silt brought by the yearly flooding of the Nile River
