Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
Natufian culture
The Epipaleolithic Natufian culture () existed from around 12,000 to 9,500 BC or 13,050 to 7,550 BC in the Levant, a region in the Eastern Mediterranean. The culture was unusual in that it supported a sedentary or semi-sedentary population even before the introduction of agriculture. The Natufian communities may be the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. Natufians founded Jericho which may be the oldest city in the world. Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. The world's oldest evidence of bread-making has been found at Shubayqa 1, a 14,500 year old site in Jordan's northeastern desert. In addition, the oldest known evidence of beer, dating to approximately 13,000 BP, was found at the Raqefet Cave in the Carmel Mountains near Haifa in Israel, in which it was used by the semi-nomadic Natufians for ritual feasting.
