"The data tell us that our galaxy, with its roughly 200 billion stars, has at least 46 billion Earth-size planets, and that's not counting Earth-size planets that orbit farther away from their stars in the habitable zone."
46 billion Earths -- not in the whole universe but in our own Milky Way!
With a number like that, it seems a statistical impossibility that we could be alone in the universe. Not only are we not alone, we're probably one vanishingly small entry in a densely crowded field of life.
Alone? Not by a long shot.
