I believe in ghost in a weird sort of way but aliens....... there may be some but i don't believe any of them have visited earth like some of you guys are saying like you seen one. I mean if they visited earth would they stay and try to do something not just take off i mean CNN would be all over that shit and. OH yeah the aliens that you have seen are they hot because i hope that if there are aliens they are hot aliens that like to smoke weed.
