What does everyone think of. UFO'S. and where did we come from.
In my opinion, I think UFO's do exist. However, I don't believe in the meaning most people relate with. UFO'S are simply unidentified flying objects from the sky and their origin is not known. The story about them being from the aliens may be just a myth or hypothesis. Check out http://en.wikipedia.org/wiki/Unidentified_flying_object#Extraterrestrial_hypothesis.
I think that there could certainly be life on other planets... the universe is huge. Not sure about UFOs, but everyone has an opinion. I want to believe we came from God, as I'm a Christian, but I also want to believe in evolution.
