If God is something of another world, He would not have to be made up of matter. Matter is of this world. The worldly restrictions (created by God) simply don't matter outside of this world. For instance, if you were building a LEGO city, everything in that city was plastic. If the LEGO people could think, they would eventually realize that everything in their world is plastic. However, you, the creator, is not plastic. You are made something from ANOTHER world (outside of their LEGO world). Just because you aren't plastic, doesn't mean you don't exist. You said matter is of this world, well, that's not true. The whole universe is made of matter. And if your God-thingy does exist, he must be found in this universe. Our universe is expanding thousands of kilometres a day. So if God would be "outside" our time and matteruniverse, he would have been squashed by now. There's simply NO WAY that a thing without time and matter can exist. ps. The universe-expandingtheory is "proof" that our universe began extremely small. That's where the Big Bangtheory started and as a result of that theory, we can explain how time and matter started. But remember these are ALL THEORIES!!!!!!!!!!!!!!! There is NO PROOF is this and there will never be any proof. But this is more proof than any religion will ever give...
