- How events might have occurred:
After allowing Edith Keeler to die, Kirk resigns his commission in Starfleet. He returns to his parents' farm in Iowa and becomes heavily involved with Agro-Engineering. As a personal favor, Captain Robert Wesley takes command of the Enterprise.
After sacrificing himself to save the Enterprise, Spock transfers his katra to Doctor McCoy. But unlike the actual timeline, Spock's body is never retrieved from the Genesis Planet and it is lost when the planet destructs.
When the Cetacean Probe reached Earth, nothing could stop it and all life on Earth is wiped out. The Federation Council and Starfleet Command are relocated to Vulcan.
--Back to the Present--
Having shown him that his choices in life did matter, the Organians return Kirk to the present time and he dies with a smile of satisfaction.
