Vulcan civilization is ancient. In "Amok Time", Spock says that the place of "Koon-ut-kal-if-fee" has been held by his family for 2,000 years. In the TOS episode "The Savage Curtain", the image of Surak speaks of a time when Vulcan war nearly destroyed them, before logic was embraced as a way of life.
