I don't; that's the whole point. Parallel universes in ST exist in the same continuity, or else we wouldn't have characters interacting with the Mirror Universe, characters from the Prime ending up in the Abramsverse, etc. The Abramsverse is created by Nero going back in time, which is a result of Nero going into the black hole, which is something that took place in the Prime timeline. Thus, events in the Prime timeline influenced the alternate timeline, because events in the Prime timeline led to the creation of the alternate timeline. But this is only the basic premise of the film. It cannot be credibly ignored just because soneone wants to pretend that parallel universes can't influence one another in any way. "His" timeline? What does that even mean? There are only two timelines at issue here: the Prime and the alternate. The Prime timeline does not end when Spock and Nero go back in time. And once again, he "affects" the alternate timeline just by showing up in 2233, before he takes any action. We do know that the Abramsverse is the result of Nero's arrival, because Orci said so ( for those who insist on throwing out the dialogue in the film which intentionally conveys the same idea to the audience, some of which comes from Spock Prime, who can't be ignored by using the "he doesn't know what's going on" ploy ). Yes, he does, despite the fact that you continue to misrepresent his position. He said that ST09 was the "butterfly". ( But even if he had expressed a different position, it remains unclear why his opinion would have overruled the writer of the film ).
