"God" is, minimally, that which exists as the ground of conceptual and ontological relationality (i.e., as the transcendent conceptual and ontological "limit value") for all things, such that they exist as conceptually and ontologically coherent, discrete-yet-relative entities.
All things exist, transcendentally, in conceptual and ontological relation to all other things as discrete "co-entities" in the total field of being. Indeed, even the total field of being is a coherent "entity" only insofar as it transcendentally relates to non-being––being so radically existent as to transcend the categories of finite being––for its very definition (in both the conceptual and ontological sense of 'definition').
Therefore, God exists.
(This borders on viewing God as the observer which collapses (collapsed?) the quantum wave which brought our universe into actual existence, but I refrain from going there at this juncture, and perhaps at any juncture.)
