Query: Search for Terrestrial Intelligence   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).
