I can't believe you like the idea of discovering alien life so you can use the discovery to troll religions. Surely there's other reasons why this is exciting?!
Even a negative finding holds important implications: if we successfully survey all of the exoplanets within 100 to 1000 light years and find no life or anything even close being habitable for humans, then it would gravely inform us of the ways in which we must preserve the Earth that we have.
