Alone Theme

On a recent viewing of our movie I was struck by a theme a single theme and 'alone' theme. *We are introduced to singular Sacrificial Engineer. *Shaw first appears as a solitary explorer fing another cave map(showing a solo Engineer pointing to thye stars) *David seemingly the only awake crew member on the Prometheus *ONe Beheaded Engineer that can't quite grasp tyhe new world he is shown in the lab *The Last Engineer who is the only survivior at a installation filled with many buildings and ships *Weyland who had the largest organization in the world..many emplayees no close friends and ultimately saw his life drifting away wiped out by his only created friend being used as a battery ram. Our final scene shows Shaw last Human crew member with a anfroid seemingly the last creration of man traveling to the Engineer's world. I couldn't help to think of Ripley heading back to earth alone with a xeno. I think the theme is more about each entity being alone with themselves as they face each step of their life. Not so much what challenge they face but how they respond to that challenge.
