Do you belive Aliens?

If anyone uses his/her common sense, S/he will get an answer that it is quite possible that Aliens exist in this universe. On our earth there are so many proofs available that indicates that Aliens not only exist but they have also visited us. Most of the people do not want to accept it because they do not want to come out of their "easy go" life. Even I had initiated a discussion on the same topic, if you have time check that one, I am sure you will like that discussion. Check my profile, it will be in the list. You can also search it in mylot discussions, topic name is "What are aliens or UFOs? Does god Exist?"

I think that the universe is so vast, there HAS to be intelligent life out there somewhere. Having said that, I think people who claim to have been abducted by aliens probably enjoyed a serious drinking session before the alleged "abduction" took place. It'll be interesting to see what happens if we do meet alien life, though. What's to stop them being a violent race and over-running Earth? Or maybe they see us as primitive cavemen in comparison to their level of technology or form of society? I would also be very interested to see the effect it would have on our religions - what happens to faiths that believe that we are totally alone and unique in the universe?
