There are two general ways to approach this question: based on historical evidence and inquiry or based on religious tradition.
Historical Evidence and Inquiry
The first five books of The Bible (Genesis, Exodus, Leviticus, Numbers and Deuteronomy) are traditionally ascribed to Moses as having written them during the Exodus from Egypt. The Bible confidently states that Moses led the Israelites out of Egypt 480 years before the fourth year of Solomon's reign, which would therefore be approximately 1444 BCE. Because archaeological evidence has made the traditional date of the Exodus untenable, some liberal Christians have suggested that the Exodus really took place shortly before 1200 BCE, when Israelites are known to have begun to arrive in the Palestinian hinterland. Modern Jews generally believe an intermediate date of round 1313 BCE.
However, biblical scholars say that Moses was not really the author of the five books, also known collectively as the Pentateuch. Scholars say they were written by a number of authors or sources over a period of several centuries during the first millennium BCE. The main sources of the Pentateuch were:
