A policeman sees a drunk man searching for something under a streetlight and asks what the drunk has lost. He says he lost his keys and they both look under the streetlight together. After a few minutes the policeman asks if he is sure he lost them here, and the drunk replies, no, and that he lost them in the park. The policeman asks why he is searching here, and the drunk replies, "this is where the light is".[1] Science very thoroughly follows the drunkard principle, because there is no sense in looking at places were you unable to find anything. Science is looking for what it can possible see. It cannot see a bacteria under ice of Enceladus, so it doesn't even try. But it can see sometimes gases around Enceladus, so it looks for them. https://en.wikipedia.org/wiki/Streetlight_effect https://en.wikipedia.org/wiki/Streetlight_effect
