Hi Rrhain,
One of the most telling anachronisms in the Pentateuch is Genesis 36:31, which actually has two anachronisms.
These were the kings who reigned in Edom before any Israelite king reigned
This really needs to have been written during or after the beginning of the monarchy, about 450 years after the Exodus by biblical dating. So there is no way that Moses could have written this.
Also, there is no evidence of any kingdoms of Moab or Edom before c. 1300 BCE. Therefore, we have two anachronisms in the one statement, neither claim could have been made by Moses.
Of course, this assumes that Moses even existed.
I also find it surprising that the Bible does not record the full name of Judaism's greatest ever prophet.
Brian.
