Not to be pedantic, but isn't the thread evidence for creationism? How the earth came about may not fit under the topic of evolution, but it undoubtedly fits under the topic of creationism.
That said, taking a creation myth and trying your best to make it line up with current knowledge, with hindsight, then proclaiming that as evidence that the writers of the creation myth actually had that current knowledge, is a long way from evidence. It's at about the same level as 'proof' that Nostradamus really was prescient and predicting the future, or 'proof' that the Bible code is accurate. Use a creation myth to explain stuff we don't know, then have that explanation confirmed later on, and I might start thinking you're on to something. (I still want to know what the creationists here think of the Bible code, btw)
What about all the other stories in a similar vein? Whether other Babylonian stories about the same gods, or other bible stories like those about Noah or Moses? Don't they have to be made to fit actual facts, too? Or is it sufficient that you can make one story fit, and call that evidence, while all the ones that don't fit, they're merely stories?
I reckon with a bit of effort, I could probably make some Chaucer look like a description of some quantum mechanics, of something like describing the superposition of two atoms. Should that be considered evidence that Chaucer actually knew about stuff first discovered centuries after his death?
I think I could certainly make some Australian Aboriginal creation myths read as allegories for the actual way things like kangaroos evolved. Is that evidence that long before Dawrwin boarded the Beagle, his theories were already known here?
The logic behind your supposed evidence is ridiculous. Even more so when a quick examination says that the supposed accurate description is anything but. Whether it's the earth as a water covered ball, birds appearing before flowering plants, the sun begetting all the planets, but having mercury-proto earth give birth to them all, that Uranus formed from Saturn, and Neptune from Uranus.
