Extra-terrestrial life does not mean Alien Vehicles at super-light speed darting in and out of the atmosphere or nerosphere. It means looking for signs of life forms on other planets or planetary systems. We could have alien life on Mars, Io, extra-solar planets, etc. They search for that.
Many astronomers and physicists have engaged in speculations about extraterrestrial life. They also use some radio telescope time for SETI (search for extraterrestrial intelligence) projects.
