"UFOs do not exist" are not the words of the author, but of government authorities. The evidence revealed here should once and for all expose this long standing lie. Are alien beings capable of abducting humans and implanting objects into our bodies that we do not know about? The evidence is the implants themselves - tiny metallic objects of unusual composition, surgically removed from people who have claimed to have histories of alien abduction. Presented here is the most advanced research on the reality of alien implants, coming directly from eminent scientists. The author, an actual doctor, had originally thought such implants were nothing more than a joke - until he found the evidence. Since doing so, Roger Leir has been the only person to share these other-worldly objects with both scientists and the general public. Thousands of suspected pieces of alien craft, soil samples and trace landing evidence have been tested, but none have revealed scientific proof indicating off-world origin. For the first time, revealed in this book, scientists have made legitimate off-world claims and proven it. Also covers worldwide sightings, what they mean, and the latest findings surrounding the amazing 1996 Varginha, Brazil crash case, where the author has traveled to investigate first-hand. Includes a Foreword by Apollo 14 astronaut Edgar Mitchell, who describes what it's like to set foot on another celestial body, and shares opinions on intelligent life in the universe. This book takes the next step in the study of other life forms that may be visiting our earth and leaving evidence. From the Foreword, Edgar Mitchell says, "In spite of denials and serious efforts by many governments to deny, the evidence has continued to mount for alien presence and activities. The learned and intelligent citizenry is becoming convinced that, indeed, our Earth is being visited by an advanced technological species." Concerning Dr. Leir's discovery of implants in humans, the TV documentary Unsealed: Alien Files stated, "With multiple labs confirming the objects are extraterrestrial, the only question that remains is: "What's the ultimate purpose of these implants?" This groundbreaking book is a must for those seeking the answers.
