Prometheus - Minor spoilers

Saw Ridley Scott's Prometheus. Was very taken by some of the philosophical ideas in it. Felt more like the heart of Blade Runner was injected into the Alien universe. One line that I can't seem to shake a particular scene. 

 

One of the scientists gets drunk, disappointed with the initial findings on the planet they're exploring. He was hoping for a chance to ask humanity's creators "Why did you make us?"  The android of the movie turns to him and replies,"Well , why did you create me?"  Amused at the question, he said "Because we could." His drunken insensitivity toward the android seems almost tragically cruel and almost justifies what follows later. He passes the scientist a fresh glass of champagne "Imagine how disappointed you would be to hear the same answer."

Humanity spends a lot of time contemplating our own existence. Why are we here and what the *** are we doing? are questions that are never too far from the mind of many people I hang out with. What if the answers are as simple as looking at ourselves. If your child asked you "Why did you make me?" what would you tell them? If you are a writer/artist/musician/filmmaker, and your work could ask you (NOT "why do you create", …BUT) "Why did you create me?"

How would you answer?
