The study of paranormal activity has a long and interesting history.
Many ancient religions are based on paranormal study, while the metaphysics of many ancient cultures included pantheons of ghosts, demons, fairies, gods and other supernatural phenomenon.
In fact, among the earliest references of ghosts can be found in the Bible's Old Testament.
A good example is in the First Book of Samuel (28:7), where King Saul consults the ghost of the dead priest and prophet, Samuel.
In the New Testament, Jesus Christ himself was considered as a "Holy Ghost" when he rose up from the dead and appeared before his 12 disciples.
In ancient Greece, Homer's works, the Oddyssey and the Illiad held many references to Ghosts and Specters prophesying and giving advice to Greek heroes.
In Tibet, Buddhist monks wrote the Bardo Thodol as a way of helping the human soul reach Nirvana after death, and to prevent the process of rebirth.
Given these examples, it's unreasonable to say that the study of paranormal activity is relatively new. In truth, it's been around since the dawn of civilization.
The only difference is that paranormal investigators in the modern world must prove the existence of the supernatural by using the scientific method, and the presentation of evidence.
