Yeah but you just need to think about what we look like and how we came about and look at the combination of things that helped (distance to the star, liquid water bombardment, moon regulation, Jupiter protection, time) to feel it's very unlikely there isn't just one other planet with these and at least cockroaches: that's enough to say we're not alone. And finding these alien cockroaches even if it take millions of years of travel, would still change everything. To see another life, you imagine ? We need to try. I know they re trying to build telescope with enough resolution to see seasonal color changes in tree leaves from here, that would be really cool.
