Why Greek, Roman and Norse mythologies are overused, where others rarely get used?
It’s interesting that so many religions from all around the world has a ‘big flooding’ story in it.
I also think that it’s interesting. And I wonder if it’s something shared by the “collective memory” of humankind, or if it’s just that flooding events are so common and impactful that any culture is almost certain to develop that myth, given enough time.
