I can't help but draw even more parallels between this and At the Mountains of Madness everytime I see the trailer.
Both stories start up with an expedition that takes the crew to a remote location (Antarctica, Zeta Reticuli II) in the hopes of learning about something primordial. Both journeys will completely change the way wee see human biology and life in the universe. However, as our characters explore this ancient, grotesque and titanic ruins, something goes wrong. Something awakens within these ruins, which poses a huge threat to the explorers.
We next learn about a race of highly advanced engineers that may or may not be a direct threat to our civilization, but the real danger lies in something THEY created. Whether in Prometheus the jockey race is actually the one that is going back to Earth with a deadly cargo or not remains to be seen, but the theme is still the same. There are far more horrifying things in the universe than Space Jockeys and Elder Gods
