Are we alone in the universe?

I seriously doubt that we are alone. The universe is huge and it doesn't make sense that we are alone and life did not arise anyplace else.

Well although I do think that UFO's may exist but on the other hand I am also very pessimistic about it. it can be that some where in this universe there maybe some other life that is more advanced than us, but we will never know unless we develop the technology that can help in reaching them further. Just imagine if we land on their planet, they turn out to be from the stone age! Lol. Interesting really.

I think there is only one universe and it is composed of some galaxies, and whatever more. I cannot surmise as of now, the possibility of other beings living someplace else. But, those scientists say that there is a possibility considering all those laser cut stones dating some millions of years ago.
