While it is logical to assume, as the ancients did, that there must be a being who is the wisest; a being who is the most compassionate; a being who is the most intelligent; a being who is the most forgiving; and on into the endless list of attributes generally listed for God. While any quality you could name which has levels of attainment must be possessed by some being more than any other, to assume that all these “bests” reside in one being takes a huge leap of faith.
It would appear that there is no logical basis for making such a leap when you examine the problem of evil. How could an all-knowing, all-powerful, all-good being permit evil to exist? This question has been around long enough to have a name — theodicy. None of the arguments for a being with these 3 qualities stand up to the rigors of logical analysis. Add in even more qualities, and you can only WISH such a being were real.
This is why none of the current monotheisms really are compatible with science, as science (when it is done right) is based on logic, and these religions require an illogical leap of faith. The one exception that I have seen is Discordianism, which holds that the Supreme Being is a Goddess of Chaos and Whimsy and which requires that its adherents do not believe anything that they read.
If your Divine One has whimsy, then She does not need to be the Best in every attribute.
