This is a very well-made video on the subject of whether we’re alone in the universe.

I wonder how others are struck by the argument that we should be looking for microbes, not civilizations? The filmmaker argues that civilizations last for only a blip in time, while microbes are around for billions of years. I think civilization as a phenomenon might be a bit longer-lived than he credits it. In fact, we don’t really know how long we can expect a civilization, much less a technological civilization, to last seeing as we are still in the very early days of both.
