The Farragut wasn't wasn't destroyed on screen. Therefor your theory is just as bunk.
Fortuantly, more evidence supports my, and everyone elses', theory than yours.
It isn't a theory. It's a statement of fact. The Farragut wasn't destroyed onscreen. Are you being intentionally dense?
Fine.
Neither Kirks father nor Spock's mother were killed on screen either.
Sure, events occured that implied an impending death, but we never saw them "die."
I therefor propose that Kirk's father and Spock's mother are both alive.
I also propose that Kirk and McCoy landed in the shuttlebay and then magically appeared in Sickbay. Afterall, we never SAW them get OFF the shuttle, walk down the hall, enter a turbolift and get off the sickbay's deck.
It's also possible Kirk was immaculately concieved.
Afterall, we never SAW Mr and Mrs. Kirk get dirty. So we've no proof that that guy was Kirk's father.
