1) it would be a visceral demonstration of the fragility of life on Earth
2) overnight, it would shift our estimate of the likelihood of life forming into "terrifyingly likely". Terrifying, because if life forms on any planet even roughly like Earth, the idea of aliens showing up one day and killing us all is suddenly horribly plausible.
