But in the narrative of this movie, both he and Spock literally "fall out of the sky". Everything they were and everything they are comes from literally another world. All the great answers you want, they are in that world. The movie doesn't take place there. They are just dropped into this one and start screwing it up.
What you really want would have disrupted that narrative, because they aren't telling us the story of that world. They are telling us the story of this one.
