On God What if belief is taken to be a frame of reference. It may just be another context for perspective developed in relation to certain information. As such, it would account for the many faiths, religions, etc and would be impossible to invalidate without concrete proof which reveals otherwise. Also, as a frame of reference, it can be tagged to new facts or information e.g. God created the atoms, quarks, etc., God develops humans through evolution, or God is involved in whatever we discover or invent in the future,...
Since God is not presented as a being to observe and point to as, "hey, there he is," but is supposed to be evident through a distinct set of circumstances and activities, therefore, whichever interpretation is given of God, if it doesn't match up to the original defining information, then it outlines a different circumstance or activity and therefore a different identity other than God. This applies to all who question why an omni-scient/potent/present God can't or isn't this or that. Just by having limitations in the question, they have already excluded the omni-scient/potent/present God they hoped to refer to.
In this way, it's about how we relate to information about God that determines for each individual whether God exists or doesn't. To me, this seems like a reasonable and practical way to perceive belief. Any takers?
