I don't know what you saw but I do believe that in this vast universe there must be more to life than us mere young humans!! I have seen so many pics, vids etc. pointing towards extra terrestrial life (obviously with loads of hoaxes and rubbishing by media). There is even the occasional physical evidence that has been found i.e. one was where a ufo landed and soil samples checked which showed some interesting findings (I can't recall exactly, this was a few years ago). Anyway, recently here by us some guys from the NSRI (National Sea Rescue Inst.) reported a UFO and the media (radio) reported it in a joking manner. What a shame... Anyway, my belief will definitely be leaning more towards the fact that in this old universe there must be far more advanced lifeforms with technology that we can't even dream of yet. Until proven without a doubt (or until governments lets up) we can only guess, unless you're that individual who has seen something that without a doubt, is real.
