Most devout Jews, Christians, and Muslims believe that Moses wrote whole the Torah, including Genesis. Genesis takes place over 200 years before Moses’ birth. so how did he do it? It seems to me that he likely had the help of written records left behind by Joseph. Joseph was made vizier of Egypt at 30 and lived 80 more years, so he likely learned to write in Egypt or had access to scribes since he was a political figure. Then Moses who was raised in Pharaoh’s house for 40 years, would have learned to read and write in Egyptian and had access to Joseph’s writings.
