Ancient history
The span of recorded history is roughly 5,000-5,500 years, with cuneiform possibly being the oldest form of writing. Genetic evidence, however, points to the first appearance of human beings about 150,000 years ago. There is also a growing body of evidence that Homo sapiens first left Africa about 60,000 years ago. For further information about human origins, see Evolution of Homo sapiens.
