Paleolithic and Neolithic periods

Paleolithic and Neolithic periods

Archaeological evidence indicates that a developed Egyptian society and culture extended far beyond the borders of unified Egypt into prehistory (see Predynastic Egypt). The Nile River, around which much of the population of the country clusters, has been the lifeline for Egyptian culture since nomadic hunter-gatherers began living along the Nile during the Pleistocene. Traces of these early people appear in the form of artifacts and rock carvings along the terraces of the Nile and in the oases.

Along the Nile, in the 11th millennium BC, a grain-grinding culture using the earliest type of sickle blades had been replaced by another culture of hunters, fishers, and gathering people using stone tools. Evidence also indicates human habitation and cattle herding in the southwestern corner of Egypt, near the Sudan border, before 8000 BC. Geological evidence and computer climate modeling studies suggest that natural climate changes around 8000 BC began to desiccate the extensive pastoral lands of northern Africa, eventually forming the Sahara (c.2500 BC). Early tribes in the region naturally tended to aggregate close to the Nile River where they developed a settled agricultural economy and more centralized society. There is evidence of pastoralism and cultivation of cereals in the East Sahara in the 7th millennium BC.

Continued desiccation forced the early ancestors of the Egyptians to settle around the Nile more permanently and forced them to adapt a more sedentary lifestyle. However, the period from 9,000 to 6,000 BC has left very little in the way of archaeological evidence. By about 6000 BC, organized agriculture and large building construction had appeared in the Nile Valley.^[1] At this time, Egyptians in the southwestern corner of Egypt were herding cattle and also constructing large buildings. Mortar was in use by 4000 BC. The Predynastic Period continues through this time, variously held to begin with the Naqada culture..
