Unfortunately none of this is controversial from a Christian perspective because the biblical document records that the descendants of the survivors went on to establish multiple nations one of which indeed was the birthplace of Abraham.
It is most likely that the Biblical tale comes from the Babylonian version, of whom the Babylonians for centuries were key players in the history of the Hebrews leading to the time of the first books of the Bible being written, in which it too was adapted from an even earlier Sumerian original like what is found in the Eridu Genesis. This does not mean the Biblical tales are not valuable companions, but the reality is the closer to the source we are to the original the closer we are to the actual facts.
As a believer in the God of Abraham I would like to point out that it appears that you and others are failing to address the distinction that according to Hebrew tradition Moses got the flood story from the God who had caused it. And as far as the influence of Abraham’s homeland the Israelite’s who escaped Egypt knew nothing of the Babylonian Myths.
However I do recognize that this is just a part of a greater work and I hope that you deal with when the Books of the Torah are thought to have been written and by whom in the larger work.
What it means to the faithful is that there was an actual catastrophic flood with few survivors who later went on to diversify into different cultures and nations.Quote
The connections are beyond reproach and universally accepted even by religious scholars. No one doubts they share a connection, the only argument, to the faithful anyway, is "what does it mean".
Thanks for sharing your work Thanos. :-)
