Atheist or Agnostic?

Atheist or Agnostic?
 
It’s odd that the word ‘atheist’ even exists. I don’t play golf. Is there a word for non-golf players? Do non-golf players gather and strategize? Do non-skiers have a word and come together and talk about the fact that they don’t ski? I don’t—I can’t do that. I can’t gather around and talk about how much everybody in the room doesn’t believe in God. I just don’t—I don’t have the energy for that.
