No. Are you paying attention? It is being said TO BELIEVERS "god does not exist". Forum is not people saying 'I think god doesn't exist". Where have you been?That question would bother me, if I were an atheist, tbh. I mean, if I say that I don't believe in ''god'', then it seems pretty plain to me. No concept of ''god''..
When they argue with a believer about their FACT that God does not exist, what are they arguing? What is that thing god which they are certain does not exist?
