@Eight Bits:
Actually, it is evidence against Gods via
inductive reasoning. Which is rather limited, and can't provide definitive proof, but it's a start to claim evidence, like Skeptic Ginger does. In fact, all that's been said on that topic is induction, just without calling it by name so far, unless I've missed anything.
In essence, if every pig we've seen so far is clearly incapable of flight, let's say a billion of them, when someone comes and says their celestial pig, let's call it Pigasus, flies... there is no reason to just assume that yeah, that one surely flies. Unless they show the evidence.
Doubly so when you also have some understanding on the anatomy and evolution of a pig, like we have for God myths.
Does it say that absolutely there is no God out there? No. But it says that there probably isn't. And especially that for any given God story, the probability is very very very low to be true. Even if there is one, whatever particular God you're thinking of is probably not the one. And this time I'm using "probably" as in actual probabilities.
Now that was just simple induction. We could go a bit more rigorous with Bayes and go for example, "what is the probability that a god exists, given that he has attributes X, Y and Z". That will actually give you an even lower probability for stories which rehash elements only associated with Gods known to be made up.
And again, doubly so when you understand the anatomy and evolution of such myths, just like in the flying pig example.
Interestingly, though, it would give you a higher probability -- worst case, just the prior -- for divine being that run contrary to normal divine expectations and don't quite fit our understanding of divine myths, like for example Yog Sothoth. (Well, Cthulhu too, but Yog Sothoth is an actual god

) I mean, come on, who makes up a Son Of God as lame as Wilbur Whateley? Though for example his mom Lavinia Whateley may well have been a virgin, as no actual sex is mentioned or arguably even possible between her and the loose collection of giant glowing globes that is Yog Sothoth, so that would be a common myth element.
So I guess the distinguished scholar Abdul Al Hazred might have been onto something
But even simple induction is still a strike against any particular God myth being true. And at the very least to make it even clearer that the one going against all existing evidence is the one who has the burden of proof.
