The obvious answer is, of course, that these planets with intelligent life could be so far away that even at the speed of light it would take thousands or tens of thousands or even hundreds of thousands of years for them to reach us.
But consider that many experts think there could be at least tens of billions of planets out there - or perhaps many, many times that.
That would mean that there is a strong likelihood that there is intelligent life out there, and that there are civilizations that precede us by perhaps millions of years.
By now, some civilizations surely would have developed the technologies to contact other worlds, travel to other worlds, or send out transmissions to other worlds.
But humanity has yet to make any contact with anyone out there?
Why is this?
Given the numbers, wouldn't it be a good guess that we should have heard from someone by now?
Is there really life out there?
