Is Xenomorph the "GOD" of the engineers?

Seems like an awful amount of artistic effort for a warning label, but then again, so is the giant skull on the top of the dome, which nobody noticed. I think if an adult Ellen Ripley were to turn up in the Sulaco (this scene is set during her childhood, it would seem)... she would not only nuke the site from orbit, but she wouldn't bother to wait until these idiots were evacuated. Her phrase "did IQs drop sharply?" would be appropriate commentary on the collective intelligence of this expedition.
