Yes, some of the earliest info was orally transmitted. However your statement here is incorrect:
Moses wrote down what had previously been passed down orally.
Some of the info was oral. But other items in the book of Genesis were no doubt gleaned from written records. Stephen says in Acts 7 that Moses was educated in all the wisdom of the Egyptians; presumably this means being able to read and write what was in their libraries.
In addition,editor-surveyor correctly says Moses had the benefit of direct revelation as well which is stated many times in the Pentateuch.
Information that is passed on orally is in a constant state of change. It is totally unreliable for any honest purpose.
This has been proven in learned studies many times. Often the message becomes completely inverted, or degenerates into gibberish within less than 10 exchanges.
well .. then we agree !
because the earliest info .. was the creation story!
The creation story HAD to of been passed down orally, and to a MUCH more primitive man than Moses, and certainly more primitive than us living here in the 21 century!
Heck even in Jesus’s time they were still talking about germs as “evil spirits” !!
Did Jesus know that germs were not “evil spirits”? absolutely ! But he had to talk to the people in a way THEY could understand!
The exact same way a scientist would adjust how he describes something very complicated to a child!
