Aliens DO NOT EXIST! More like government agents dressed up like aliens to kidnap you and inspect your anus so you can tell the world you've been abducted and look like a moron. All theory's scientists have tried when trying to figure out how they would get to another terrestrial planet like earth have failed, and always will all possibilities are just to many billions of miles away for us to ever reach them with out dying of old age first same goes for aliens. The only possibilities for aliens would be evolved humans traveling back in time if you believe that's possible.
