The argument David Kipling made seems reasonable. Statistically the chance if there being almost no civilisations or the universe just teeming with life are the biggest. The parameters have to be tweaked just right for there being just a few civilizations in a galaxy. It's not teeming with signals and chances of parameters being just right is low, so most probable is we being alone.
