Actually, he said "at best it's a hypothesis", and he's not shifting the "burden of proof" (You are turning into Skippy) since there can be no scientific proof in the matter.<quoted text>
Hey Dude that's a bit goofy calling Atheism a hypothesis.
It's more like a non statement isn't it?
It's exactly like you are trying to shift the burden of proof when you are making the claim. That's sort of revealing.
You can not prove that no gods exist any more than someone else could prove that the Christian God does exist.
Such proof would be beyond the ability of science.
However, what is NOT beyond the ability to science is to demonstrate that Ramses, who was a god, actually did exist.
Now, if you'd like to present evidence that Ramses did not exist, I'd love to see it.
