The concept of God is impossible to prove either the existence or the nonexistence of: however, a method might exist for the evaluation of "gods" as they are described in the holy books that house the details of their character and actions, for only god in abstract is unprovable but by a sort of flavor learned us by their actions we might be able to dismiss different gods as petty, incompetent, impotent and short-sighted - this is part of the reason why the old ancient gods were so easy to dismiss - they were riddled with all sorts of imperfect qualities to the point where belief in them denoted blind lunacy. God has stepped out of the abstract, out of which nothing can be said, and into a verifiable realm where he is not invulnerable to betraying himself. The method seems to have been used throughout history without being formalized or inscribed for all to see...denial of another religions gods is a necessary condition of subscribing to one over the other (minus universalists) so a great many people have had experience with this across history. Can such a systematized god denying method exist to disprove all gods and not just the ones a particular group identifies with?
