Does believing in ghosts mean that God exists too?

OK, I am a professed atheist and have been for a long time. But I also like watching shows like Ghost Adventures and Ghost Hunters and the like. I know they are just tv shows made for entertainment but I really do believe ghosts are possible. Which leads me to think well if I believe ghosts are possible then that means life exists in some form after death which leads me to think maybe God does exist after all. Have I been wrong all these years? is it possible to believe that ghosts can exist but not believe in a God? what are your thoughts on this?
