From prehistoric UFO sightings, cave paintings, and ancient astronauts to modern sightings around the world, this book explores claims of aliens living among us, abductions of humans to alien spacecraft, and accounts of cooperation between extraterrestrial and humans since the UFO crash in Roswell—along with evidence of what the government knows and what it has covered up. Investigated by Kevin Randle with a curious but critical eye, here are more than 100 sightings, events, and discoveries of alien influence on human events throughout history.
