Do you believe in alien life - that is life that occurs outside of Earth and didn't come from Earth?
I think that there is a very good possibility that it is out there. 
The Drake equation is a theory that speculates about the existence of intelligent life in the universe - I wonder if they are right.
I do know that the chances we are alone in the universe are slim.  Maybe we will find someone on Mars one day
Since the mid 20th century there has been an ongoing search for signs of alien life - i wonder if they are keeping stuff from us.
There is the whole Area 51 thing.  I am sure they are hiding something
It's actually had a major cultural impact - mostly in works of science fiction - just think of all the movies that deal with aliens.
True.  Some of my favorites have aliens in them.  I always liked Independence Day.  I sure hope the aliens we meet are nicer than the ones in that movie
Oh I think mine will have to be Alien, even though it cameout in 1979, it's just iconic.
