"Çatalhöyük ( also Çatal Höyük ...) was a very large Neolithic and Chalcolithic settlement in southern Anatolia, which existed from approximately 7500 BCE to 5700 BCE ." - Wikipedia
So, despite the age of this site, people had already been living in towns in Anatolia for an enormously long time when this massacre happened, in fact for longer than the time from then to now.
It still boggles my mind that Catal Huyuk was around nearly 3000 years, destroyed (apparently by an attacking force), and the small successor settlement built nearby only lasted about 50 years — and that all this ended nearly 7000 years ago. The destruction of CH was attributed by Ryan and Pitman to the ingress of refugees fleeing the Black Sea flood (pretty good suggestion, IMHO).
