You are still not quite on the right track.
You are thinking of things "happening" -- define that word. It means something that wasn't going on is now going on, it is in the process of "happening" -- meaning that an event in space is occurring through time. How can you say that something happened when there was no time and no space?
Even by giving the "creator" a sense of "always" you once again violate the lack of time domain. Even the name "creator" or "eternal being" implies the time domain... as in "creating" something or "always existing" -- as in eternal.
The simple answer here is that you, I, and everyone else cannot EVER understand or even think about such things. Any way that we can discuss or ponder the situation is wrong, as we think of things in 4 dimensional time and space, period. This is just how our brain is made, because we exist and experience 4 dimensional time space and nothing else.
see what you are saying make sense but i think you can go another level beyond that, and say that if there was nothing, (not even god) beyond space and time, before the formation of the universe, then there would be no formation of the universe...
it's impossible to think of time and space coming from nothing because it's impossible period.
but if some force did somehow(which we cannot grasp) live outside the bounds of space and time, then the formation of the universe becomes VERY possible and even likely..
not to mention, a being without the bounds of time and space would be (by definition) ommipresent, and omnipotent he would litterally have no bounds by our standards because every boundary in our universe is a basic result of our existence in time and space.
this also explains the concept of the holy trinity (which i believe)...
god the father is the part of god, eternal, also the one who created the universe
god the son is the human version of himself that god sent into the bounds of space and time as one of us (fully god, but fully man)
the holy spirit is gods unexplainable presence as an eternal being in a world based on time and space... the holy spirit is everywhere and every time at one time (by our views) its not like the son, because the son was bound by time and space, the spirit is not...
again these are just inevitable results of a god existing outside time and space
think of it kinda like a video tape, we are watching the TV with one event progressing after the other (in time)
but this "GOD" would be taking the tape out and looking at the entire film strip
