Atheistically
There is no doubt that the Israelites had inherited, borrowed or adapted many stories from Mesopotamia, but it need NOT NECESSARILY BE ALL AT THE BABYLONIAN EXILE.
sorry1: I just need to emphasize this point.)
The Mesopotamian culture, religion and myth had spread all the way to the Levant, including Palestine, as early as the mid-2nd millennium BCE, as well as all the way to the Hittite Empire in the northwest and Egypt in the southeast.
Tablets found in Egypt and the Hittite of the Gilgamesh's epic demonstrate the popularity of the Akkadian-Babylonian literature. Like I wrote early, there are fragments found in Megiddo, Palestine; the biggest fragment coincided with the narrative of Tablet VII (Death of Enkidu) of the Standard Version.
Due to the popularity of Mesopotamian legend in the Near East, they could have infiltrate the Palestine at any point time, since the 14th century BCE.
According to the Documentary Hypothesis, there are 2 versions of the Noah's Flood story had been redacted and edited into one (rather) inconsistent myth: J (c. mid-10th century BCE) and P (c. 500 BCE) sources.
So not the whole flood story come from the Babylonian Exile period.
I don't remember which parts were from which sources: the rain lasted for 40-day-and-40-night version or 150-day version. All I remember is that the part of the size for the construction of the Ark (Genesis 6) and God's covenant to Noah (not to send another flood to wipe out the Earth) come from Priestly source.
You misunderstood me bud. I agree with your post 100%.
I was only giving one example of how the final redaction took place, and have mentioned the multiple accounts we have. I also stated it didnt originate after the exile.
