I have had not a few argue that the genesis flood came before Gilgamensh. It's obvious why they think so. It reads more like recorded history than the obvious myth of Gilgamensh. But the more primitive Ark and the more localised Flood and selection of domestic animals (the vermin can look after themselves) makes the Sumerian version look earlier than the Genesis version which seems more aware of shipbuilding and the wider world requiring more species to be saved (1) indicates that the Genesis version of the Flood was much later borrowing from Babylon. Which is probably where the Bible writers (looking for an origin tale to make the Jews the original people) got Genesis and Exodus, because hints like Sargon provided the story of Moses in the Bulrushes, not to mention similar gerbling of historical records like AhMoses directing the semitic tribes into Canaan, and the reference to the Philistines making the exodus - story post Ramesses III at leas. And maybe Babylonian historical records provided the slightly wrong history of the fall of Babylon to Persia (Babylon was not destroyed but the 'Chalcdean magi' were still the wise men of the Middle east in Seleucid and even Roman times) used to construct the 'prophecy' of Daniel, plus the more accurate history of their own time (just before the Maccabean revolt) but that's just another guess, like my other guesses
.
But all in a heap folks, all the evidence points to the Bible Not being the first version of all the origin legends, and Israel and the Hebrews Not even being a people in Canaan until after the 11th c. B.C. And the claim that the Bible, Eden and Flood came first is just like everything in Bible - apologetics - Fiddling the evidence to try to make it support the Bible, and then dismissing it when it doesn't.
(1) even though they had no idea that this was so many, even . And maybe even without the dinosaurs having to be on the Ark, too (2) so that (despite Woodmorappe trying to cram all species into a few cattle trucks) they had to invent the
Baryma explanation which was a few basic 'animal kinds' that super - evolved over a thousand years or so (3) which is where Flood apologetics has pretty much ended up - Evolution and deep time geology, speeded up like a Benny Hill sketch and looking just as hilarious.
(2) one point leads to another...I always wondered why on earth the Creationists didn't use the Flood to explain the extinction of the dinosaurs. I found out that it was the discovery of dinosaur tracks in supposed Flood levels of rock strata that meant the Dinos (and ALL the previous prehistoric critters) had to be on the Ark, too. And no Creationists even knew why, or even thought about it. They simply repeated what their propaganda says without giving it any thought. I swear this is true - they recite the Dogma, no question or research. Though the ones who "Might otherwise have been wise" (and will be, once they deconvert) may try to make the dogma work, with theories made up on the hoof.
(3) Sorry folks, but the strange ramifications of YE Creationist apologetics is fascinating, ...pretty much the same with Flood geology. After attempts to deny the geology, they end up having to propose Geology as it happened, (Breakup of Pangaea, pushing up of mountain ranges) but all done over a couple of months or
even weeks from the waters 'going down' (actually mountains going up) and the repositioning of the continents with all the appropriately sorted animals in new and old world monkeys, and the marsupials assigned to Australia. With Pangaea breaking up
after the creation of the mountains that resulted from the breakup of Pangaea. But, like the mountains 'arising' as the water went down, the hydroplate theory has the mountains already there and revealed by the water going down - where to? That was what the mountains rising was supposed to explain, but the mountains already there means the water still has to go somewhere. We know what's going on - some
ad hoc hypotheses with some 'science fact' that sounds likely assigned without much thought, folks, to give it scientific credibility.
