- First, they argue that the existence must originate in some sort of necessary being.
- Second, they argue that this necessary being must be omnipotent - must have power without limit.
- Third, they argue that this being must be a person.
- Fourth, they argue the this being must have great intelligence (to account for the design of the universe) - indeed must be omniscient.
- Fifth, they argue that this being must also be omnibenevolent - supremely good.
But then there are many omnipotent and omniscient gods that might account for the existence, fine-tuned character, and so on of the universe. Including e.g. an evil God, belief in which we all still rightly consider absurd, not withstanding that the exact same sort of cumulative case can be made for him (differing only in that final step). Are we then close to establishing the existence of an evil God? Of course not.
