Yes I believe in aliens and i do belive they have visted earth before

Well there is not proof they exist, but also there is nothing to say they dont.

Humans have only explored not even a tiny fraction of space, most likely there will be other life out there, somewhere, but the chances are we will never come across them...

Aliens totally exist..

nobody belives dinasours exists... but hey.. look at the museums.. what do you find? ..

DINASOUR BOWNES.. that is proof that aliens exist

NUFF SAID

I don't believe in aliens. It doesn't seem that aliens exist, and it just seems unlikely that they would exist.

I dont think there are aliens but who knows there always could be other life forms out there.

XD i think aliens dont exist but it would be cool.

Yah, go down to the mexican border.

^ those are ILLEGAL aliens. i honestly think aliens from another dimension are real. it just seems like there are other forms of life then us on earth.

Um , if alien exist what will they do ?
it's seem no other lifeform in space cuz there's no water and air ...

It seems unlikely that aliens wouldn't exist.
When people think aliens, they think of life forms similar to us.
The probability of there being other forms of life outside of planet earth: 1 out of 1. It's been discovered; look up some articles on archaea.
The probability of there being other life forms outside of planet earth similar to ours? Much less.
