Given that Moses (an Egyptian name) would have lived around about the 12th century BCE, the stories were written some 500 years later - and modified during and after the Neo-Babylonian captivity and exile. And each part was influenced according to which group of scribes was responsible for writing it and in its subsequent editing. (The Watchtower is an amateur when it comes to amending the texts.)
I am currently wearing my fingers down to my elbows collecting and collating material about the early Israelites. At the rate I am going, I suspect it will take me up to a month to cobble my first draft.
I can help if you need any. I am also very interested in historiography and in the development of monotheism.
