While Ridley Scott’s sequel to Covenant is apparently on indefinite hold, the timeline for the franchise is open-ended.
It’s getting quite complicated in there, so we’ve put together a handy year-by-year (or millennium-by-millennium) guide to Prometheus, Alien: Covenant, Alien, Aliens, Alien³ and Alien Resurrection so you won’t be too confused by the time the next sequel/prequel arrives.
And, for completists, we’ve also mentioned the Alien vs Predator movies (sorry about that).
Here’s the story so far for the Alienfranchise.
4 billion – 2 million BC – An alien race, later dubbed “The Engineers”, visit Earth and leave one of their own behind. His body breaks down after he drinks black goo, and his DNA enters the water, recombining to create life.
20th Century Fox
35,000 BC – Evidence of the Engineers in Scotland.
3590 BC – Sumerian evidence of Engineers’ visit to Earth.
2470 BC – Egyptian evidence of Engineers’ visit to Earth.
1540 BC – Babylonian evidence of Engineers’ visit to Earth.
