"Then the engineers are big, but not as big as the space jockeys, then the engineers made humans, but not the aliens, David the droid made the aliens, then there's black goo, the goo is what made the humans, but it's also a chemical weapon that kills the engineers, then there's a white alien fsr, then there's some rift between the engineers, then there's a war, it's all David's fault and the goo, maybe there's two kinds of black goo, they keep it in things that look like alien eggs, but they're not, they're just urns.
