do you believe in aliens?

I donot know if they exist.But I prefer to believe somewhere they are talking with each other like our human beings.And i have readed many books and photos which show that they have been the earth.

they say that it's true, some of the scientific study that aliens do exists, i've seen it on tv. but for me, i believe that there are moving things beside our earth planet, there are nine planets in the whole universe, and i think that there is another planet which has its moving creature too, that is called aliens

I do believe life do exist in other places other than earth. After reading about various science fictions, I do think may be life does exist in the outer places. I think there are evidences that shows that aliens does exist. I think there are lots of things in the world that we still doesn't know.

I do believe there will be aliens in the universe. The universe is unlimited and everything can be possible. Perhaps it is another different kind of life in somewhere. I love China

Yes i believe in aliens, because of the probability principle, there should be at least a few thousand of advance civilization in our galaxy alone. how much more in the other galaxies?
