Something without? In any place where we can't seem to fill with science, instead we fill with a god. This arguement doesn't work as then you would have to tell me who created god and who created the creator of god. Just because we don't understand certain things doesn't mean we have to fill the vacancies with the idea of some supernatural being.
i dont think you understand what i wrote. something without means, something not within or something other then the unverse to describe the existence of the universe. im not getting back in to the reasons i beleive it to be god. but, due to the theory of relativity, you dont have access from this universe to others, nor to anything "outside" so this is a gap that will always remain void. we wont know why, or how to an extent. quantum gravity, when figured out may change this.
the who created god argument has already been answered by me.
god needs no creator, nor does a universe without the dimension of time as we know it. before only exists because time does, we know time had a beginning, hence there never was a before the big bang. its impossible to grasp and full of paradoxes but it is proven by science, and logic.
so if you assume the big bang was the start, its out of nothing, or it always existed in the conditions it had. and then for no reason the conditions changed. the only thing that can change conditions when they are set or remain the same is intelligence.
