I don't think that's the way most people think about God. The search for God is primitive and stems from a desire to explain the ultimate origin of things. Certainly the Greek mythology was of this type. Judaic theology was much more sophisticated, centering as it does on the creation of the universe. The origin of that religion did not stem from believing in everything, but from trying to explain everything.
Or as Einstein put it:
"I'm not an atheist and I don't think I can call myself a pantheist. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangements of the books, but doesn't know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God."
