I’d be more suspicious of the Genesis story if NOBODY talked about the Flood before Moses.
So I don’t get how earlier versions or names in different languages (or changed in order to make cultural claims) cast doubt?

Because it means the story is not Jewish or Christian but was borrowed/co-opted during the Jewish captivity in Babylon.
It would then validate Sumerian and Babylonian Gods, not the Judaic God. It would mean the early Jews were just stealing it and making it up as they went along.
