We already know that there are countless billions of alien planets out there. We just never had the technology to spot them. Even knowing they are there is probably meaningless because we could never reach them and it is quite likely that no intelligent species are there with the technology to recieve any messages (either they are behind us in development or way past us-in which case they would most likely be here already). Its cool that they can find them, but it really doesn't get us any closer to finding life outside our own.
Debator: To believe that God made the incomprehensible universe and filled it with NOTHING for 13 billion years is mind-blowing. And then he picked one and ONLY one planet to start fucking around, creating things and then destroying it with asteroids and ice ages and other incredible catastrophes for 4 billion years. I mean, to believe in God and to believe that is simply an astonishing believe in him wasting a lot of space for nothing.
