Main article: Prehistoric EgyptThere is evidence of rock carvings along the Nile terraces and in desert oases. In the 10th millennium BC, a culture of hunter-gatherers and fishers replaced a grain-grinding culture. Climate changes and/or overgrazing around 8000 BC began to desiccate the pastoral lands of Egypt, forming the Sahara. Meaning to say that these things are older then your grandma and her dog too. Early tribal peoples migrated to the Nile River where they developed a settled agricultural economy and more centralized society. Because who else builds Pyramids? am I right!
By about 6000 BC, a Neolithic culture rooted in the Nile Valley. During the Neolithic era, several predynastic cultures developed independently in Upper and Lower Egypt. The Badarian culture and the successor Naqada series are generally regarded as precursors to dynastic Egypt. The earliest known Lower Egyptian site, Merimda, predates the Badarian by about seven hundred years. Where they had wine festivals and rollercoster rides. Contemporaneous Lower Egyptian communities coexisted with their southern counterparts for more than two thousand years, remaining culturally distinct, but maintaining frequent contact through trade. And eventually developed the "hey you got my stuff", "only if you have my money" type of relationsip. The earliest known evidence of Egyptian hieroglyphic inscriptions appeared during the predynastic period on Naqada III pottery vessels, dated to about 3200 BC.
