That's an interesting question. I'm familiar with 'stars are too distant', but the idea of life beyond our solar system doesn't seem to be all that strange - I think that our world is the strange one, really.
This galaxy (let alone the entire universe) is pretty complex and large, so there's a long road ahead of us discovering it. It may not exactly be like Hollywood portrays it.
To be honest, I don't have any experience with UFO's or aliens. Do you, Jimsaidhello?
