When Zeus decided to end the Bronze Age with the great deluge, Prometheus had foreseen the flood and warned his son Deucalion(descendant of Prometheus) and his wife, Pyrrha(descendant of Epimetheus) to build and ark. During the flood they landed on Mount Parnassus, sacred to Apollo and the muses. When the flood subsided and they were on solid ground again Deucalion consulted an oracle of Themis about how to repopulate the Earth
Ridley said he had Michael Fassbender throw rocks to show time had passed while waiting for Oram to birth the Xenomorph. However I find it interesting that it of lined up with this myth. Deucalion was told to throw the bones of his mother behind his shoulder. Deucalion and Pyrrha interpreted “mother” to be Gaia, ancestral mother of all life, and the “bones” to be rocks. They threw the rocks behind their shoulders, which soon began to lose their hardness and change form. Their mass grew greater, and the beginnings of human form emerged.
The parts that were soft and moist became skin, the veins of the rock became people’s veins, and the hardest parts of the rocks became bones. The stones thrown by Pyrrha became women; those thrown by Deucalion became men.
After David releases the pathogen their craft crash lands on a mountainside just like Deucalion’s Ark, and with the population destroyed it is David’s plan to repopulate this second Eden with his creations. Unfortunately without the consent of Elizabeth Shaw, his mother figure dissected and utilized with the accelerant.
