2210 – Amanda Grayson, Spock’s mother, is born on Earth.
2230 – Spock is born. Amanda Grayson is 20 and Sarek is 65. Problematic tbh.
2233 – James T. Kirk is born. Just for context, in the divergent timeline of the reboot movies the Romulan terrorist Nero arrives from the future on the Narada, destroys the USS Kelvin and kills George Kirk. Everything after this point doesn’t apply to the reboot timeline, but… that’s a separate article.
2245 – The USS Enterprise (NCC-1701) is launched under the command of Robert M. April.
2254 – The USS Enterprise visits the planet Talos IV while under the command of Captain Christopher Pike. Spock is already serving aboard the vessel at this time. Although the Talosians attempt to capture the crew, they are able to escape. It’s all detailed in “The Menagerie” (TOS 1×15-16).
