Somewhere in some other planet, orbiting some very distant star, maybe in a another galaxy, there could well be entities that are at least as intelligent as we are, and are interested in science. It's not impossible; I think there probably are lots.
はるか遠くにある恒星のまわりを公転している別の惑星 ― おそらく別の銀河にある惑星の どこかに 我々と同じような知性をもつ生命が実在して 科学に興味があるでしょう　否定はできません　たぶん多いでしょう
