How about: other planets with well developped life are really special and unique. For example: lava rivers and lavafalls, diamond rains, no light reaching the planet, weather so extreme that all life is buried deep underground and many more. Basically, every planet is filled with uncommon traits but they all have something in common. Things so typical that you could successfully look for them on every second planet.
Somehow, all those most popular traits gathered together make Earth. And that’snot normal.
