Then along came people with names like Newton, Galileo, and Einstein, and all of a sudden we weren't so special any more. Neither is our insignificant little pebble orbiting a nondescript sun tucked away in a far corner of a pretty ordinary galaxy.
The point is this. Given the immensity of the Universe and our own ordinariness, I find it impossible to believe that life arose ONLY on our pebble.

I don't think that is central to the debate , it is more a mater of how common, a large number of things had to occur just so for the condition for organic life as we know it to happen here, how common is the occurrence of "intelligent life ? we only have one data point = pure speculation on top of speculation add to that the speculation on the possibility/ probability of interstellar travel , more speculation.
