On the phenomenon of alien abductions, the testimonies are now incalculable: confessions, stories and sworn memorials of men and women from all parts of the world and from every social class who claim to have seen, talked and walked with men from other worlds. These people have exposed themselves in the first person by speaking publicly about their experiences, opening our eyes to an unknown but no less real phenomenon. The border experiences of these witnesses have been studied by great international experts, who have judged them credible. The marks on their bodies were subjected to medical examinations, while the objects they had under their skin, analyzed by forensic laboratories, revealed non-terrestrial origins. Reading the testimonies, evidence and considerations of the researchers, the authenticity of the abductions phenomenon emerges in all its facets.
