1) One passage describes a sequence of events; a later passage states that they happened in a different order. Presumably Moses would have remembered the proper sequence.
2) In the story of the Flood, one passage has Noah collecting two of each species while another passage states that he collected 14. One verse describes water coming from the heavens and from below the ground; another describes all of the water falling as rain. The duration of the rain differs between two verses.
3) Genesis 11:31 describes Abraham as living in the city Ur, and identifies that location with the Chaldeans. But the Chaldeans did not exist as a tribe at the time of Abraham; they rose to power much later, in the 1st millennium B.C.
4) Deuteronomy 34 describes the death of Moses. It is difficult to attribute the description of a funeral to the deceased.
5) One passage in Genesis 33 has Jacob legally purchasing the location of Shechem for the capital of the northern kingdom of Israel. Genesis 34 has Jacob's sons killing all of the men of Shechem by a deceitful trick.
6) The first part of the story in Numbers 25 about the rebellion at Peor referred to Moabite women; the second part said that they were Midianites.
7) Moses is described as going to the Tabernacle in a passage where the Tabernacle had not yet been built.
8) A list of Edomite kings included some monarchs who were in power after Moses' death.
9) Some locations are identified by names that were invented long after the death of Moses. One example is seen in Genesis 14:14; it refers to the city of Dan. That name did not exist until a long time after Moses' death.
10) There are many verses in the Torah that state that something has lasted "to this day". That appears to have been written by a writer who composed the passages at a much later date.
11) Numbers 12:3 states "Now the man Moses was very humble, more than all men who were on the face of the earth." (NKJ) If Moses were that humble, it is unlikely that he would have described himself in these terms.
12) Deuteronomy 34:10 states "There has never been another prophet like Moses..." (NLT) This sounds like a passage written long after Moses' death.
