Where did I ever
say they needed to come to Earth? We have a lot
of telescopes pointed at the sky, which are getting more powerful all the time, and we've never seen even one tiny shred of evidence for intelligent life outside Earth.
If there is intelligent life out there, there is some reason we haven't found it: it's too far away (meaning it is relatively rare), it is not capable of interstellar flight (which means it is difficult enough that hardly anyone can do it), or it simply never exists contemporaneously with us (again, pointing to the rarity or at least short-lived nature of such civilizations.)
