Aliens yes, ET life anyway. Aliens coming down to earth and kidnapping people for perverted experiments may be a little far fetched. Ghosts, no idea, but theres somethings out there that people cant explain. I do have a doubt about ghosts and think that they could all be a load of mumbo Jumbo. You may all laugh at this for now but I bet when you wake up alone at 3 am you start pi$$in yer pants.
I know I do.
