What is the most important sentence spoken in prometheus?

To me its "THAT IS WHAT I CHOOSE TO BELIEVE". As that is what its all about - nobody knows it all, or even enough to KNOW what is really going on, so we have to CHOOSE what we want to believe... hopefully we choose depending on plausibilty - but as human beeings are so damn to emotions and fear, mostly emotions dictate what to choose... The funny thing about that is - most people CONFOUND what they choose to belive with truth. Thats a big and interesting message, but prometheus could make this much more clearer, i think they did not want to annoy religious people - hopefully they are more unfearful in the sequel!
