The authors discuss Carter's formula (1974) about the mankind evolution probability following the derivation proposed by Barrow and Tipler (1986). They stress the relation between the existence of billions of galaxies and the evolution of at least one intelligent life, whose living time is not trivial, all over the Universe. The authors show that the existence probability and the lifetime of a civilization depend not only on the evolutionary critical steps, but also on the number of places where the life can arise. In the light of these results, they propose a stronger version of Anthropic Principle.
