The first major comprehensive draft of Genesis was composed by the Yahwist in the late 7th or the 6th century BC, during the Babylonian captivity, with later additions made by the priestly source in the post-exilic period [REF].
Calculations based on the Septuagint have traditionally dated creation to around 5500 BC, while the Samaritan Torah produces a date around 4300 BC, and the Masoretic a date around 4000 BC [REF].
