Extra teristerial

When i was younger I use to believe in aliens but now I know that they were just someones imagination. But now that they have changed the way movies and tv show are it kind of makes you wonder if they are really real or not.

I don't believe that the planet Earth is the only planet with living creatures in the entire vastness of outer space. I also believe that, at some point, someone will have the ability to visit here or we will develop the technology to travel far enough to visit others but I don't think contact will be made. I believe that people on this planet would freak out too much if ET came calling and the response would be a violent one.
