you take the scientific community as a source of truth. This is an appeal to authority, who are abstract and undefined. It lends discrete if one believes them relevant to the truth of the proposed statement, but i do not believe that this abstract entity has any relevance to this argument. To be more clear, this scientific community has about as much possibility as god.

this does nothing to disprove the existence of a god. an explanation for why such a concept may have been created does not disprove the god.

of course he does, he is non-existing, therefore asking whether or not he exists is pointless. You cannot ask if an incorporeal thing exists, since by its definition, it does not.
