The Fall of Man:
In Islamic and Christian doctrine, the fall of man, or simply the fall, refers to the transition of the first humans from a state of innocent obedience to God to a state of guilty disobedience to God. In Genesis: Chapter 3, Adam and Eve live at first with God in a paradise, but the serpent tempts them into eating the fruit from the tree of knowledge of good and evil, which God forbade. After doing so they become ashamed of their nakedness and God consequently expelled them from paradise [to Earth, where they gave rise to humankind].
See any similarities to the ship [presumably] leaving that Engineer behind to create humanity?
