I have no doubt that civilizations are out there. Maybe a handful, maybe nearing infinity. But out there.
The problem is "out there" is so far away, we are all isolated on our own island worlds. An ocean of space so vast we cannot meaningfully traverse it with probes or radio, to say nothing of manned interstellar flight.
But it never gets boring for me to imagine what other civilizations there might be, and how they might be different from us and from each other.
