  The existence of intelligent extraterrestrial life forms among the thousands
of billions of galaxies that dance in the Universe is beyond doubt. Meeting
with one of them is only a matter of time. SETI (Search for Extraterrestrial
Intelligence) has been searching for them for only half a century. However, the
crucial question today is whether we will have time to establish contact given
the multiple threats that humanity puts on itself. Therefore, it seems urgent
to launch a program complementary to SETI which could be called STI (Search for
Terrestrial Intelligence).
