Then that means the universe couldn't come into existence. You can't have time if there isn't time. What you are saying implies a eternal stand still. Thus requiring a creator to set the clock in motion
The problem with this line of thinking is that it's a double-edged sword. If, as you put it, time needs a creator and thus god is the creator then, and that if everything in existence needs a creator, then what created god. It's a pretty common question asked: If god is eternal, then what created god?
But one question everyone ignores is what makes god so much more special that he doesn't need a creator, and just 'always was'. God living in the supernatural world, someplace in the sky beyond our ability to measure in this life, gets an easy way out with the answer that he always existed. But why does he always get an easy way out. No one can account for 'god's creation', but just reply that he has always existed.
If space-time-gravity began at the beginning of the big bang, then what created it? Perhaps the singularity that is said to have existed that expanded into our present day universe. Cosmology and the fine folks at NASA and at CERN have done a great job in researching the earliest stages of our universe and are currently working on getting beyond the planck epoch - to the very beginning of the universes' expansion, and to which it will show how the universe could have expanded. to create space-time-gravity.
Another argument is 'How can a universe come from nothing'. Lawrence Krauss have given a lecture about how it is possible for such a thing to happen. Here's the video:
So far there is no need for a creator to create the universe. There is no force needed other than science to set the clock in motion. Saying so opens up a giant can of worms for creationists (whether young earthers, old earthers, day-gappers, etc) to account for the creation of their own personal reason to whom they hold accountable for the creation of this universe.
Then again, why the double standard? Why does god get an easy way out of 'always existing', but that what predates space-time-gravity, doesn't?
I think before the last big bang there was another one, and another and another, in an endless cycle of explosion, expansion, contraction, explosion...
