The Alien Book: A Guide to Extraterrestrial Beings on Earth

These days, when we think of an alien, we conjure up an image of a black-eyed, large-headed, dwarfish being that has come to be known as a Grey. Greys have become a staple part of pop-culture, never mind just the field of UFO research. They’ve appeared in Steven Spielberg’s Close Encounters of the Third Kind. They regularly popped up in The X-Files. And there are numerous people – all across the world – who claim to have been abducted by them. Yet, before the 1950s, these Greys didnt exist. Instead aliens came in all sizes, shapes, and bodies. This book investigates them all, along with eyewitness accounts of the people who have seen them. There’s an absolute plethora of alien entities. Some are benign and others downright deadly. Some are small, like a germ or virus that has NASA creating guidelines to deal with an outbreak of an extraterrestrial germ. Some are big like a giant praying mantis or the biblical Goliath. Covering hundreds of extraterrestrial life forms in more than 40 thematic chapters, this is an absorbing look at the mysteries of aliens on earth.
