A religion question plz read!?

"IF" a creator do exists. You know how in religions they portray the Creator as something that's perfect right? I was thinking why would anyone create anything, it cannot be without some sort of inclination, or reason. Nothing is done without either desire or necessity. Since the omnipotent Creator can neither desire nor feel necessity because he is "perfect" and "complete" in himself and cannot want or need anything outside his own self. Basically what I'm saying is if somthing desires something it means it's lacking something right and something that's perfect and complete cannot lack anything. If The creator needed to make us then that's an necessity and if the creator wanted then that's a desire. U feel me, Maybe religion is wrong, I say that because how can somthing imperfect tell other imperfect things what's perfect? Think about that, and this...the concept of "God" was originally created because of natural disasters, ancient civilizations thought they occurred because of "Gods" getting pissed off when they do something wrong. What u do you all think?
