Most of the truly ancient signs of civilization seem to have begun in Anatolia. From Gobekli Tepe already mentioned to Nevali Cori, Karahan Tepe, Cayonu and on to
Çatalhöyük - Wikipedia .
Not entirely.
The Natufian settlements in Palestine and the Levant south of Anatolia were making bread and beer over a 1000 years before Gobekli Tepe was built - or any of the other stone monuments in southern Anatolia.
Shiekh-e-Abad (modern name) a neolithic farming village in (modern) western Iran had shrines decorated with animal horns in the houses, one of the earliest indicators anywhere of Personal Religion.
The Nabta Playa oasis/early lake site in the Egyptian desert had deep wells for year-round water, built their houses in straight lines (urban planning?) and around 6400 BCE built a stone circle astronomical calendar (not as impressive as Stonehenge, but definitely a sign of 'civilization')
Mehrgahr in modern Pakistan was one of the first agricultural settlements in south Asia, had the earliest indications of domesticated cattle anywhere, made ornamented pottery and personal jewelry with turquoise and lapis lazuli and sea shells (all imported, so organized long-distance Trade)
And people in the American Southwest were already starting to modify a primitive potato plant into a prime food source around 9000 BCE, so Botanical Engineering started early and far away from Anatolia!
And I'll see your Catalhoyuk and raise with Jericho, which was a stone-walled city almost 2000 years before Catal was settled, complete with a stone 'citadel' tower - and was located in Palestine, well south of Anatolia.
In fact, there were similar early signs of 'civilization;' - or at least, proto-city organization and habitation - springing up in Anatolia, the Levant, Egypt, Mesopotamia, northwestern India, and north-central China at roughly similar times between 9500 and 5000 BCE, and it seems like every year somebody uncovers indications of another early site that sends all the archeologists back to their computers to rewrite heir conclusions.
