Pinotti reassumes in this book his decennial experience of investigator in the extraterrestrial intelligence field offering, in a new scientific historical perspective, the elements in order to found, in an objective way, one new discipline: the paleoastronautics. Basing on a precise context of archaeological elements, cultural traditions and historical witnessings, the author reaches the hypothesis that since always, for better or for worse, intelligences of other worlds have interacted with humanity, leaving very visible traces of their contacts.

Not only: these ancient presences would appear directly connected with the phenomenon known as UFOs. A perhaps provocative vision, but from the solid scientific bases it implies the possibility that, in the past, a biological union between Homo sapìens and the mysterious visitors from the sky, later made Gods from our own ancestors following a cultural process, has occurred.

The presence of extraterrestrial intelligences that periodically visit our planet in order to observe is by now, asserts the author, scientifically sure. In this book, UFO expert Pinotti, makes the point on fifty years of analysis of the UFO phenomenon in the past, basing himself rigorously on tested facts and documents, verified from CUN and the Italian Air Force.
