Humans can't live with them. Can't leave them in charge of a billion-dollar spacecraft hurtling through the cosmos. As the old saying goes, back in 1979, Ridley Scott and his team introduced us to HR Giger's monstrous, unsettlingly phallic starbeast that we would come to know as a xenomorph. The original creature, known by fans as Big Chap, was without a doubt the primary antagonist of that film, but arguably, it was not the true existential threat faced by the crew of the Nostromo.
In 'Alien,' two deciding factors brought Big Chap aboard the ship: the crew and the company, later named Weyland-Yutani. The company sends the Nostromo to LV-426, the moon where they'll discover the alien eggs that lead to their downfall. The ship's computer, Mother, wakes up the crew upon picking up the signal, and the company's rules demand they stop to investigate. This new mission is pushed by Ash, secretly an android with a mission to bring back an alien organism.
Prometheus (2012), a prequel to Alien, features the crew of the Prometheus venturing to LV-223 after archaeologists Elizabeth Shaw and Charlie Holloway discover an ancient star map, believed to be an invitation from the engineers who kickstarted humanity. Fueled by Peter Weyland's quest for eternal life, the mission ends in failure, marked by the deaths of most crew members due to reckless decisions and exploration of the black goo by the android David.
Alien Earth continues this theme with humanity as the true horror. The series highlights flawed human choices leading to disaster. In episode 5, the sabotage aboard the Weyland-Yutani ship Majino is an example of corporate manipulation and hubris. Meanwhile, science officer Chabuzo's negligence leads to chaos, and the sabotage by Petrovic under Prodigy CEO Boy Cavalere's command results in potential catastrophe, all driven by Cavalere's sinister motives.
Throughout the Alien franchise, from Alien to Covenant, a constant theme is humanity's hubris leading to self-inflicted disaster. The horror isn't merely the xenomorphs but the humans behind the dangerous exploitations. The memorable phrase reflects the universe’s theme: the fallibility of man serves as both narrative and warning as humanity attempts to control the incomprehensible, with each entry underscoring the persistent threat of human greed and folly.
