Your thinking is too linear - what if it was created forward and backward in time from that point? Or, to get semi-religious, what if TPTB created it at the same time as the regular universe, but in response to the transporter event that had not occurred yet?Except that in Mirror, Mirror the MU had some history developed for it that wouldn't make sense if it had been "just created." Kirk's service record had a list of his successful campaigns and that he assumed command of the Enterprise upon assassinating Pike and so on.
I'm not saying I BUY it, either. Just that I could see it, and Trek has, at times, certainly sold us worse explanations for things, no?
