 A 2009 Bayesian analysis identified an origin for Semitic languages in the Levant around 3750 BC with a later single introduction of Ge'ez from what is now South Arabia into the Horn of Africa around 800 BC, with a slightly earlier introduction into parts of North Africa and southern Spain with the founding of Phoenician colonies such as ancient Carthage in the ninth century BC and Cádiz in the tenth century BC.The earliest records of Semitic languages are from 30th century BC Mesopotamia.Other theories include origins in the Arabian Peninsula or North Africa.
