Aliens are believed to be living in outer space possibly on another planet. Many movies and television shows are about aliens that come to Earth. In these movies and shows, they show aliens as attacking the Earth. This makes people scared of aliens, but it also makes them believe that aliens are out there in the universe and may have tried to make contact with the people on Earth.
There have also been some rumors that the military has housed aliens that have crash landed on the Earth. This area is called Area 51. I don’t think that aliens live among us because we would know that aliens are here because of their appearance and behavior. I don’t think that aliens could immediately adjust to human life.
