I'm not so sure. I understand that, given the size of the Universe, how statistically unlikely it is that life would not exist somewhere else. And my belief system would be uninjured to find life elsewhere. And yet, I also believe we may be unique. We have been listening for radio signals for decades, and found none. The large, gaseous planets outside our orbit protect us from debris. So does our moon. The gentleness of Earth's climate over the past few million years, and few hundred million years, has allowed intelligent life to evolve. There are a myriad of considerations suggesting that intelligent life may be more unlikely than pure statistics would predict.
