. A creator of the physical universe must exist outside the physical world (or he'd have to create himself which is nonsense). Since time exists only in the physical universe by definition a creator cannot be subject to time, time does not exist for him, he exists apart from the physical universe. So it is not irrational to say the creator always existed.
1/. Where was this creator before the universe existed? 2/. where is that creator located now?
