What is humanity’s search for extraterrestrial intelligence?

Answer 1

One of the programs is called SETI, an acromyn for (S)earch for (E)xtra(T)errestrial (I)ntelligence. You can read about it here: http://www.seti.org/ or you can even participate by looking here: http://setiathome.berkeley.edu/.

Most of the searching is looking for electronic signatures of intelligence with radio telescopes.

Answer 2

What is it? A better way to phrase your question would be "What are some of mankind's methods currently in use to detect extraterrestrial intelligence?" or "Is mankind's preoccupation with the search for extraterrestrial intelligence futile?" Try those and you may get better results.
