I strongly believe that there are aliens out there, somewhere. Not sure what they look like, though. I really doubt they are green like they are in sci-fi movies（科幻电影）. I also don’t think they look like us. But I’m sure they exist. I just don’t think we’ll ever see any or find any. They live too far away. If you think about it logically, there have to be aliens out there.
All a planet needs are to be warm and have water and life will exist. There are billions and billions of planets in the universe, so there are probably millions and millions that have life. Alien life. It’s also likely that some of the aliens are much more intelligent than we are. I wonder what we’d do if really intelligent aliens visited Earth. What would we ask them?
