Then what is 'rational' to you Anti-Guv? That there is no 'God'? If anything, that's irrational, because the universe didn't create itself. A creator of design itself is at play here.
God is the beginning and the end. He is the motion of existence itself. That's not irrational.
I said irrational OR irrelevant. By example, a capricious god would be rationally consistent with the observed universe, but would be irrelevant from a practical standpoint because he would be impulsive and unpredictable.
What is not rationally consistent is an omnipotent, omniscient god who creates anything that he considers evil.
PS. Unless the omnipotent, omniscient god creates a self-modifying universe to which he's then indifferent, which would make him an indifferent god, who would be irrelevant to us from a practical standpoint. The same would hold true if the god were not indifferent but ceased to exist (died) for whatever reason. Would be rational, and quite interesting, but irrelevant.
