Wouldn't you be a bit lonely if you were the only thing that existed and you were self aware and you had no beginning and no ending?
What is God without a creation? What are the "godly" attributes of might, power, justice, sovereignty, mercy, love with nothing upon which those attributes can act?
If we accept that one of the attributes of God is "The Creator" and God is perfect, then without a creation God's perfection is not realised therefore God would not be perfect. If one of the attributes of God is not "The Creator" and God is perfect, then if there was a creation it would mean God is imperfect because something exists that is not one of his attributes. Therefore if God exists and creation exists it follows that one of the attributes of God is "The Creator". Given a creation does exist (and creation is an attribute of humans (e.g. the creative arts), and according to all religion humanity is made in God's image) it follows that if God exists then one of his attributes is "The Creator"
One can readily argue that the universe can exist without God existing, but one cannot really argue that God can exist without a creation. If God existed without a creation we would not exist and hence we could not be having this debate about God and creation.
I'm not sure why you find this so hard to understand.
If you are trying to suggest that a God with infinite knowledge and power can't exist because such a being would never make any sort of creation because it would know everything about everything before it happened, well this is simply an illogical line of reasoning given no one is a supreme being so no one can really understand how a supreme being would think. It would be like an and trying to understand the motivations and actions of humans.
However in some religions texts a reason is given, e.g. "I loved thy creation, hence I created thee. Wherefore do thou love Me that I may name thy name and fill thy soul with the spirit of life." So perhaps the principle motivation of God is love, if the reader believes such religious texts to be legitimate.
