Ghost do not exist. However, I get a kick out of folks, who call themselves scientist, thinking they know it all and therefore, it must be as they claim it would be. Like when others claim there is other life out in space and fail to realize it would not have to be anything like us or breath anything like us. (There is no others but, that is besides the point of what I was saying.)
You forgot to add global cooling error, global warming err, climate change....yeah that's it scientists to the list of thinking they know it all.
