There's no way to prove we're unique in the universe. At most you could say the known universe, but even then you're going to have a hard time convincing people of that.
Known to who? I don't like this very self-referencing way of thinking. Very similar to the discovery of America... people were already in America way before Columbus came and "discovered" it. (although apparently he didn't even realize he hadn't arrived to India)
