"At least they know when God has them beat!"
There is no way to know if God exists.
The claim of certain ignorance entails a claim of omniscience, which is self-refuting.
Cordially,
"There is no way to know if God exists."
Such an absolute statement comes a God-like all-pervasive knowledge on your own part.
So, you can see in every nook and cranny of the universe, and beyond it, throughout all time, all space, in the heart of every atom, and every creature, and you can declare with absolute knowledge, "No one can know!".
Just because you don't see God doesn't mean others can't. Your statement comes from extreme arrogance and placing yourself in the position of being all knowing. Don't you see it?
