However, I absolutely hate it when people say "We are perhaps/probably/certainly alone in the universe" and then go on to explain why (they think) we are perhaps/probably/certainly alone in the galaxy. These two things are not even slightly the same! Even if there's only on average one technological civilization per galaxy (say), we might well be alone in the milky way but share the universe with a wondrous number of other civilizations.

Existence of aliens in a different galaxy has absolutely zero consequences for us now and forever. We may "share the universe" in a theoretical way, but we don't share anything in the real sense of the term.
