No-one has yet stated the obvious, that whatever scribe sat down and summarised the Jewish folk-tales, (that have become the christian accepted version of the flood story). was using the original flood story as a template.
How do we know that?
Simply from the existence of an older written history!
If any Christian is willing to challenge his/her beliefs, they will find this older flood story insightful and informative.
You have all the plot devices that the Jewish scribe used in his Genesis account.
A god bent on destruction, but willing to save some. A life-saving vessel, animals going in two by two**.

Of course, in the end we realise that both versions are the work of human imagination, just as much as any space flick which imagines alien monsters threatening humans.
