Star Trek: First Contactrevealed that the pivotal first meeting between humans and the Vulcans owes a debt to the Borg in a weird way. Directed by Jonathan Frakes, 1996’sStar Trek: First Contactwas a crowd-pleasing blockbuster that’s acknowledged as the best of theStar Trek: The Next Generationmovies.Star Trek: First Contactdepicts the heretofore unknown events leading up to how the Vulcans met the human race, which is theorigin story ofStar Trek.

InStar Trek’s timeline,First Contact Day happened on June 15, 2025. On this day, Dr. Zephram Cochrane (James Cromwell) achieved mankind’sfirst warp flight aboard his starship, the Phoenix, which caught the attention of a nearby Vulcan ship. The aliens landed on Earth to meet the humans. From that point on, with the Vulcans' help, the human race joined together as United Earth. Hunger, poverty, and the reliance on money were ended within 50 years, and Starfleet was founded to explore the galaxy, leading to the creation of the United Federation of Planets in 2161.

Star Trek’s First Contact Wouldn’t Have Happened Without The Borg

It’s A Predestination Paradox

The Borg played a pivotal role in First Contact Daybecause, as seen inStar Trek: First Contact, the cybernetic aliens time-traveled to assimilate Earth in the 21st century. Earth was in dire straits after World War III devastated the planet and any resistance was futile to the Borg. Captain Jean-Luc Picard (Patrick Stewart) of the USS Enterprise-E followed the Borg through time and destroyed the Borg Sphere, preventing their assimilation of Earth. The Borg then pivoted and attempted to take control of the Enterprise.

To maintain the timeline, the time-traveling Borg and the role the USS Enterprise-E played in Zephram Cochrane’s first warp flight were kept out of historical records.

It’s thanks to the Borg that the USS Enterprise-E jumped back to 2063 to help ensure First Contact took place as history records. While Captain Picard kept the Borg isolated on the Enterprise, Commander William Riker (Jonathan Frakes) led an away team to help the alcoholic Zephram Cochane launch the Phoenix, and Riker even flew in the Phoenix’s cockpit with Cochrane. Mankind’s successful inaugural warp flight, and the resulting First Contact with the Vulcans,may not have happened had the Borg not instigated a temporal crisis.

Enterprise’s Vulcan Flashback Retconned Star Trek History 22 Years Ago

Enterprise’s “Carbon Creek” changed what was known about when Vulcans made First Contact with humans in Star Trek history.

The NX-01 Enterprise, commanded by Captain Jonathan Archer (Scott Bakula), was ordered to intercept the Borg. Archer ultimately destroyed the Borg, although the cybernetic organisms were able to send a message to the Collective in the Delta Quadrant. However, Captain Archer’s Enterprise crew never identified the enemies they faced as"the Borg,“which preserved canon that First Contact with the Borg happens inStar Trek: The Next Generation’s 24th century. Thanks toStar Trek: First Contact, without the Borg, there’s no First Contact between humans and Vulcans.
