who created god.

Prove that the theory of relativity isn't a wild illogical claim.

Also, science is saying that the universe came from an absence of existence.
How is that not wild/illogical?

That's the most egotistical thing I've ever heard.
Nobody is exempt from proving their statements, regardless of what
they're proving.

Not all Atheists think the big bang is even correct, you need to brush up on the definition of Atheism, it isn't believing in science, it's simply a disbelief in deities.
