Archaeology throughout in the Western Desert shows a wide span of Neolithic occupation, such as in Nabta Playa where early occupation dates back to 7500 BC.[12] Nabta Playa is just 20 kilometers northwest of Gebel Ramlah, and findings from the two regions are often compared.[13] At Gebel Ramlah, the earliest known burials have been dated to the late Early Neolithic, around 6500 BC. Burials dated to the Middle and Late Neolithic are scattered throughout the area as well.
