Detecting planets is not the same as finding life. We only have one example planet with life, Us, Earth. Until we find a second source, we cannot know if there even is any other life out there. And if there is, it being intelligent life, close to earth, developing spaceflight, comming here.. IMHO Chances are very very low.
