There's no doubt that the search for planets is motivated by the search for life. Humans are interested in whether or not life evolves on other planets.

A 'serious' scientist in 1992 or 1993 had to admit the possibility that planets were really rare, that most stars might not have planets. We've gone from there to here - where most stars have planets.
