Well the paranormal would seemingly break some aspect of science and the aliens would just open up a whole bunch of things that hardly seem probable, unless they lived locally. And if that was the case I can't see why they wouldn't be living here on Earth - not such a bad place after all. For the paranormal, and similar related things, one either can believe, not believe, or have an open mind. For me, I haven't come across enough evidence to have the open mind, and I don't accept the word of others just because..
