Ricardo González Corpancho (Lima, 1974) became interested in the UFO phenomenon in 1988 when he witnessed a close sighting in Peru. Thirty years later, he has become a worldwide reference on the subject. He has traveled around the world more than a hundred times and has published twenty books. He has been dedicated to researching this enigma for a quarter of a century without interruption, and yet he claims to have more questions than answers. His contact testimony, presented at numerous international congresses and conferences, as well as in various television interviews, has sparked significant debate and interest among scholars. On eight occasions, he has invited researchers and journalists specialized in UFOs to successful "scheduled sightings." For González, the classic phrase "we are not alone in the universe" falls short. For him, we are not alone on Earth.
