Whenever the god as a first cause discussion comes up, somebody posts the rebuttal: "If everything needs a cause, then what is the cause of the creator god?".
Let's define the universe as everything that we can directly or indirectly experience. Space, time, the quantum field. Let's define god as the hypothetical resident of the hypothetical supernatural, and the supernatural as everything not belonging to the universe.
My problem is: as the creator of time and space, god does not reside in either. (Not agreeing to the previous sentence implies an immanent god, but the existence of the immanent god is true by definition.) By not belonging to time, the concept of CAUSE cannot be applied to god. It's outside context. Cause is what pre-exists and influences an event to the degree that without it the event does not occur. Take time away from the definition and the cause-effect link ceases to make sense. Cause and effect become interchangeable just by reversing the time axis. Take away time and poof, everything goes down the drain.
So, when you ask, "What is the cause of god?" you have implied that the supernatural features a super-time unidirectional axis according to which the concept "cause" can be applied to "god", which creates a meta-religion much more arbitrary than the others, because it is closely linked to the way our brain operates with time, space and logic categories.
Or, you have expressed pure nonsense, like "What is the width of envy?"
So, since people keep using this "creator of god" argument, as if nothing were amiss, I may be missing something obvious. What is it?
OT: I personally reject the "god as a necessary first cause" argument for the simple reason that I consider logic unable to derive truths in the context of the supernatural. It's a matter of belief, one can believe the universe is the ultimate abstraction from which all others stemmed, or one can believe the universe is itself an abstraction for something meta with respect to it. Occam's razor works against the first hypothesis, because it makes the universe special.
OT IN THE OT: I define the universe as an "abstraction" because I define "real" as "whatever can directly or indirectly influence us". But, then, defining the abstraction "game of chess" as a sequence of moves, what is real for the chess piece? The wooden board, no. The piece is influenced exclusively by the movement of other pieces, which is abstract for us and real for it. So, basically, real is what matches your abstraction level.
