Nabta Playa was once a large endorheic basin in the Nubian Desert, located approximately 800 kilometers south of modern-day Cairo[ 1] or about 100 kilometers west of Abu Simbel in southern Egypt,[ 2] 22.51° north, 30.73° east.[ 3] Today the region is characterized by numerous archaeological sites.[ 2] The Nabta Playa archaeological site, one of the earliest of the Egyptian Neolithic Period, is dated to circa 7500 BC.[ 4] [ 5]
Although today the western Egyptian desert is totally dry, this was not always the case. There is good evidence that there were several humid periods in the past (when up to 500 mm of rain would fall per year), the most recent one during the last interglacial and early last glaciation periods which stretched between 130,000 and 70,000 years ago. During this time, the area was a savanna and supported numerous animals such as extinct buffalo and large giraffes, varieties of antelope and gazelle. Beginning around the 10th millennium BC, this region of the Nubian Desert began to receive more rainfall, filling a lake.[ 2] Early people may have been attracted to the region due to the source of water.
Archaeological findings indicate the presence of small seasonal camps in the region dating to the 9th–8th millennia BC.[ 2] Fred Wendorf, the site's discoverer, and ethno-linguist Christopher Ehret have suggested that the people who occupied this region at that time may have been early pastoralists, or like the Saami practiced semi-pastoralism.[ 2] This is disputed by other sources as the cattle remains found at Nabta have been shown to be morphologically wild in several studies, and hunter-gatherers at the nearby Saharan site of Uan Afada in Libya were penning wild Barbary sheep, an animal that was never domesticated.[ 6] According to Michael Brass (2018) early cattle remains from Nabta Playa were wild hunted aurochs, whilst domesticated cattle were introduced to northeast Africa in the late 7th millennium BC, originating from cattle domesticated in the Euphrates valley.[ 7]
