On the subject of UFOs, I think there is most likely intelligent life out there, but that Earth hasn't experienced other intelligent beings at all.
The aliens always described are too similar to creatures on Earth. Central spine, usually bipedal organisms with a head on top with faces similar to ours...There would be so many other paths for evolution to take on other planets, so I doubt they'd be so similar.

I can agree with this. I really never looked at it like that, but I do believe with us and any other life forms in the universe (if there are other life forms) is it has to be within the habitable zone of a star, like we are to our star (the Sun). Also, circular orbits within that particular habitable zone, I think would offer the most stable planetary climates where life could exist. I also think it has to be within the range where the temperatures are right for liquid water to exist on a planets surface.
