This phenomenally simple riddle is more than just a troublesome headache for the Yahwehist. It’s an utter nightmare. In one clean coup de grâce it renders the entire fanciful concept of omnipotence invalid, and by doing so obliterates one of the most treasured attributes the Yahwehist ascribes to their god: its omni-power.
This is not, however, to say the problem is unnavigable. It can be solved, but to negotiate around the paradoxes self-annihilating properties the Yahwehist has to swallow a tremendously bitter pill and concede that their particular Middle Eastern god is not actually omnipotent. That is to say, their god’s powers are limited to logical things only, meaning it cannot perform self-contradictory tricks. It cannot fabricate a square triangle, pit an unmovable object against an unstoppable force, pen a set of all sets, produce a married bachelor, or make the currently logical universe illogical as that would allow self-contradictory things, which the Yahwehist has already admitted their god cannot do. If it could, then it could create an un-liftable rock, and since the Yahwehist claims god can lift any object, “a rock so heavy it cannot lift it” cannot exist, and therefore their god cannot create it.
The monumental flaw in this rationale is that it accepts logic (which is a law) precedes god. If the Yahwehists god is limited to logic, then that god does not determine it, engineer it, or rule over it. In two words, logic exists before and without a god. Logic (the absence of self-contradiction) therefore exists objectively and does not require a law giver, rendering the Yahwehists Prime Mover god-hypothesis irredeemably crippled.
