The prehistory of Egypt spans the period from earliest human settlement to the beginning of the Early Dynastic Period of Egypt around 3100 BC, starting with the first Pharaoh, Narmer for some egyptologists, Hor-Aha for others, (also known as Menes). This Predynastic era is traditionally equivalent to the final part of the Neolithic period beginning c. 6000 BC, and corresponds to the Naqada III period.
