   The scientific problem of the origin and development of the Homo sapiens species gives rise to another problem – the possible presence on our planet of a highly developed extraterrestrial civilization (or civilizations). A positive answer to the question of such a presence could not only solve the main puzzle of anthropogenesis, but also remove many unsolvable problems of Atlantology from the agenda. The presence of a highly developed extraterrestrial civilization could explain the planetary nature of the civilizing activity of the “Atlanteans,” and the absence of traces of the activity of their civilization, and the absence of sunken continents, and perhaps even the nature of the cataclysm of a planetary scale, now called the “Great Flood,” and the mysteries of the calendars of the ancient Mayans and Egyptians, and much more.
