The hypothesis is substantiated, according to which technological civilizations of our type can originate in the Galaxy in a ‘belt of life’, a narrow circular zone with the galactic orbit of the Sun inside. This zone is characterized by specific conditions due to the corotation circle, an exceptional region of the Galaxy, passing through it. In the belt of life birth and death of civilizations should apparently occur in spiral arms because of supernova explosions. In this case, the lifetime of a civilization is the time of its motion along Galactic orbit between the adjacent spiral arms. In 3.3 109 years our civilization will enter the Perseus arm. It can be expected that in the Galaxy the ratio of the probable number of civilizations at a higher than ours — technological level to that at a lower technological level is of the order of 0, 7.
