  Present-day Turkey has been inhabited by modern humans since the late Paleolithic period and contains some of the world's oldest Neolithic sites. Göbekli Tepe is close to 12,000 years old. Parts of Anatolia include the Fertile Crescent, an origin of agriculture. Other important Anatolian Neolithic sites include Çatalhöyük and Alaca Höyük. Neolithic Anatolian farmers differed genetically from farmers in Iran and Jordan Valley. These early Anatolian farmers also migrated into Europe, starting around 9,000 years ago. Troy 's earliest layers go back to around 4500 BC.
  
  Anatolia's historical records start with clay tablets from approximately around 2000 BC that were found in modern-day Kültepe. These tablets belonged to an Assyrian trade colony. The languages in Anatolia at that time included Hattian, Hurrian, Hittite, Luwian, and Palaic. Hattian was a language indigenous to Anatolia, with no known modern-day connections. Hurrian language was used in northern Syria. Hittite, Palaic, and Luwian languages were "the oldest written Indo-European languages ", forming the Anatolian sub-group.
  
  Hattian rulers were gradually replaced by Hittite rulers. The Hittite kingdom was a large kingdom in Central Anatolia, with its capital of Hattusa. It co-existed in Anatolia with Palaians and Luwians, approximately between 1700 and 1200 BC. As the Hittite kingdom was disintegrating, further waves of Indo-European peoples migrated from southeastern Europe, which was followed by warfare. The Thracians were also present in modern-day Turkish Thrace. It is not known if the Trojan War is based on historical events. Troy's Late Bronze Age layers matches most with Iliad ' s story.
