Proof of god

PZ Myers:

I’m a hardcore atheist, but I’m not claiming to possess absolute truth, Catholics are. I’m saying that 1) believers have failed to provide an internally consistent definition of a god that does not contradict available evidence, and 2) have failed to provide specific evidence that their god is the best possible explanation. 

Saying that “things exist” is not evidence for “my specific model for why things exist”, especially when there are better alternative models that don’t have the shortcomings of the god hypothesis. There is a fundamental distinction there that they consistently fail to notice.
