Biblical scholars say there is no doubt that Moses could not have written the Pentateuch - it even has different names in different places, for his own father-in-law. They say that the Pentateuch actually had four principal authors, all of whom were anonymous, and that it was written many centuries after the time attributed to Moses. He did not write the Pentateuch and did not write about his own death.
The first five books of the Bible, known collectively as the Pentateuch, are traditionally attributed to Moses. A well known problem with this is that the Pentateuch reports the death of Moses. One solution put forward is that God told Moses of his own future, while another, more plausible solution is that The Pentateuch was completed after his death. Another, less well known problem with authorship by Moses is that his own father-in-law is given three different names in different places. You would expect that Moses would at least know the name of his own father-in-law! In fact, scholars tell us that the Pentateuch had not one, but four different authors, and was written many centuries after the time attributed to Moses. This is why there are so many 'doublets' - passages written twice and in each case somewhat differently. It is also the reason that the writing style changes from place to place, and why early Hebrew is mixed with a later version of the Hebrew language. Moses did not write the first books of the Bible and, of course, did not write of his own death.
