The whole "creation of life" thing was stupid. Midiclorians are symbiotic, found in other lifeforms. Therefore they can never create life ex nihilo, they can only interact with existing life. And that's all they were ever reported to do in the movies. They allegedly "created" Anakin by making his mother pregnant, something no more miraculous than parthenogenesis. (Unfertilized bee eggs produce drones, which can only mate with a queen. Hey, I just discovered the genesis of the Anakin-Padme relationship!) Later, we hear midiclorians can "keep Padme from dying" of some unspecified ... death. Keeping someone from dying isn't creating life, it's extending life. When I got a shot of penicillin to cure my tertiary syphillis, it wasn't creating life, I was already alive.
