Come onn!! If WE exist then why can't some other intelligent civilization outta this planet exist? It's that simple! I've heard people say that I don't believe in aliens, blah blah blah but come onnn!! Why not?? They are not ghosts or myths that can't be believed in.... of course everyone is entitled to their own opinion but not believing in life in other planets is really dumb
