Psalm 90 is certainly attributed to Moses, and some believe that the same author wrote Psalm 91. However, Psalm 90 is most unlikely to have been written by Moses, even if moses had been a real, historical person.
The Bible says that Moses lived to 120 years old, and was already 80 years old when he began the Exodus from Egypt. The Bible also says his father lived to 137 years, so Moses would have been accustomed to people living to well beyond 100 years. Yet in Psalm 90 verse 10 the author says that the days of ouryears are three score and ten (70), and if by reason of strength they be four score years ..."
