I believe I said earlier that the only reason to think the Sumerian flood story was the original is because they had the earliest writing of anyone we know.
Hard to get oral folklore from a dead guy.
Sure, it could be Ubaid. But the Sumerians weren't just sitting around deciding whether to absorb Ubaid culture. They weren't even there at some point. If the story came to the region with them, it could have come from almost anywhere. Same for the Ubadians.
Could have been a tale told around the fire at Göbekli Tepe.
One thing's certain, the Biblical version came from Mesopotamia.
