For millennia mankind has come into contact with aliens. Whether we have called them angels, watchers, fairies or ghosts, the fact remains that these encounters are with beings alien to humanity. With all of our modern science and high-resolution digital photography, we should have gathered sufficient evidence to prove their existence - and yet, the fact remains that we have not. In truth we are no closer than we were a hundred years ago. Why is this? The answers will startle believers and non-believers alike. We will uncover the reasons there are so many similarities in the sightings across the different cultures of the globe and throughout the centuries. We will look deep into the mind of man to discover the smoking gun that has fired the bullet of belief in aliens and other unexplained phenomena. The question is, who pulled the trigger? Welcome to the inner journey of the aliens.
