I heard friends talking about the very special setup for the movie "Prometheus", a prequel to "Alien". The movie isn't about the fight between aliens and humans, instead it focuses on the relationship between the creator and created beings, as well as why humans are so interested in outer space. I haven't had time to see it yet, but am very interested in this topic.
A research scholar once hypothesized that we did not originate on Earth, instead we emigrated from outer space. Futhermore, our space exploration is because we wish to return home. I don't think this is an impossibility. I also wish to take a look at outer space as well.
