The Existence of God is Impossible

To first answer the questions you have, 1st off they are flawed. You are asking if the Universe needs a creator then a creator must intrinsically need a creator. According to the www.big-bang-theory.com "Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning." The site later goes on to say " "three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy."3 The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing. So where and in what did the singularity appear if not in space? We don't know. We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we. " Since we have science to say we have had a finite beginning science is not a very adequate measure of truth. Science is infinitely finite meaning that it can only reach as far as our minds can. We can not even begin to fathom what existed before our universe in that singularity. It is safe to assume that outside of the singularity existed God. Since God is infinite the universe could expand a googolplex over and still not reach the incredible size of God. Since science is greatly limited to our observations of our reality it is safe to say that we cannot discount the existence of God only because lack of observation. This is the quintessential fabric of Christianity which is faith. We must believe that what God says is true because we love and trust him.(Forgive me for being sentimental) In this reason their is a possibility through science that God existed outside that singularity which coincides with what you said that God must exist outside of space and time which is completely feasible. Now on to free will-you made an argument that free will that God cannot have free will. I completely agree the bible even says in Numbers 23:19 " God is not a man that he should lie nor the son of man that he should repent" God cannot do whatever he wants, which is free will. he is bound by an order which is good and right. If God was allowed to have free will he could change his mind which would create new laws,new morality. If God changed he ultimately couldn't be God. A god can exist without free will just because something doesn't have free will doesn't mean it is not a God. This assertion proves inevitably nothing. On to the offensive, without a God there would be no reason for humans to exist, We go to work to provide much like animals hunting in the wild. We reproduce to pass down our genes much like animals. But why do we humans need to exist. In fact why does all life on Earth need to exist. If we were all annihilated the Universe would continue to expand. Without a God the Universe would not need life, it would just be stars and planets and galaxies. A God gives us purpose to serve him and embody his will. Outside the singularity we don't know what was so there is a possible chance that God exist. The scientific evidence would support this that God exist outside our space time continuum. It is perfectly feasible for God to exist beyond what we know and scientific proof.
