"The evidence that the earth is being visited by at least one extraterrestrial civilization is extensive both in scope and detail. In its totality, it comprises a body of evidence which at the very least supports the general assessment that extraterrestrial life has been detected, and that a vigorous program of research and serious diplomatic initiatives is warranted." - Dr. Steven Greer, Director of CSETI (Center for the Study of Extra-Terrestrial Intelligence)

A ghost is an alleged noncorporeal manifestation of a dead person (or, rarely, an animal or object). It is often thought to be the spirit or soul of a person who has remained on Earth after death. According to some sources, a ghost may be the personality of a person after his or her death, and not tied directly to the soul or spirit. Every culture in the world carries stories about ghosts, but they vary across time and place, with disagreements both as to what ghosts are and whether they are hallucinations or a part of nature.
