Extraterrestrial civilization has made its presence known over the past decades. Perhaps the most crucial period in the life of mankind is coming, when the inhabitants of the Earth will have to determine their attitude to the growing influence of the UFO factor, and UFOs will no longer be classified as “unidentified” objects. Numerous evidence leads to these conclusions, including declassified American documents, as well as the conclusions of Russian experts. The key phrase was the phrase spoken by Academician Alexandrov in 1977: “We can no longer ignore the existence of UFOs.” What do creatures of a different formation need on Earth? What will contact with them mean for us? Will “brothers in mind” prevent humanity from going into space, or will it be possible to develop a consensus? What are the “guests” that in previous generations may have appeared in earthly history? The author, who had the opportunity to observe a foreign ship himself, seeks to give his answers and proposes to take immediate measures so that underestimation of a new factor does not lead to catastrophic consequences for our future .
