There is nothing in the desert

..and no man needs nothing. There will be various explanations of the meaning from the few lines of movie script. My interest was in when they were spoken. David says this while Prometheus is landing. In my mind that is the perfect time for this expression. It is before our adventure really begins. At this point perhaps David is the only crew member who sort of knows the future in regards to this moon and sort let's the cat out of the bag to anyone really listening. I mean if you are on an inter steller space trip and your robot starts to quote lines from a movie 140 years old an attentive crew member might sort of file that away. My interest is in the timing of the comment and it's importance in the storyline.
