Your fundamental assumption is distorted. Existence is essentially simultaneous action. Identity and individuality (which are not the same) are what explore and navigate through simultaneous action. This ability to psychically move through simultaneous action creates action within action. 

So, one single action can lead to an infinite amount of simultaneous actions. This would, of course, be impossible within a temporal-spatial existence or environment. An entity, such as your conceptions of a God entity, would exist within this nonphysical environment, just as we all do, just as you do.
