The precursors of life (polypeptides) are already found on asteroids. Life probably evolved from asteroid impact plus geothermal vent. It's probably everywhere. We aren't special. Also waterbears survive and can reproduce after exposure to space so it leads me to believe that aliens might have already arrived here, they just are not what we expected.
