Lone Engineer i början av Prometheus drack den svarta vätskan för att fröja jorden med intelligent liv. Detta beskrivs i avsnittet Prometheus Blu-Rays extras, i bildtexten för en av de raderade scenerna:
Scene 7: Arrival of the Engineers
The Engineers touch down on prehistoric Earth for a sacred ritual devoted to the seeding of Intelligent life. Whereas the Theatrical version of the scene is devoted to the Lone Sacrifice Engineer, this early cut features several of his comrades, including the Elder Engineer. The ceremony was filmed with dialogue but unsatisfied with the result, Ridley Scott removed the dialogue entirely.
