Not completely unlike but certainly more so, God is the person we perceive behind the totality of our experiences.
The superlatives are one of the ways we go beyond the limits of our personal experiences to build a better image/understanding. Ah the contradiction in that! Its like Bruce Lee’s finger in “Enter the Dragon” which he uses to point beyond what we know, and then he has smack his student, “don’t concentrate on the finger or you will miss all that heavenly glory.”
Besides this mystical crap, I think there is a rational theological point here as well. It is one thing when our superlatives reach beyond and another thing when they nail down. So sure I believe God is omnipotent and omniscient and such but when that leads to list of things you claim God cannot do then I think you have gone too far with them.
