As far as i know, gods, like the rest of the universe, consist entirely of information. They hold, and transfer information. And by information, we mean, influences upon individual decidability. The question is, what is the quality of the information that they transfer? And how do we measure the consequences of the information that they transfer? These various gods exist, since humans act as though they exist, even if they only exist, like all of the universe, as information. And some of these gods are ideal, some helpful, some unhelpful, and some nothing more than the embodiment of evil. The way we know, is the truth or falsehood of their information, the productivity or parasitism of their people, and the genetic, economic, informational, and aesthetic achievement of their people. Gods are measurable and decidable. We can JUDGE THE GODS WORTHY OR NOT.
