Extraterrestrial civilizations. What is your opinion?

Someone else is definitely sharing the universe with us. And if you imagine that it's not the only one in the world, then what do you think, could it be that only on this one little planet do intelligent beings live? I don't want to say that in the neighboring galaxy there's a Sorora and intelligent monkeys live there, but still... It seems to me that there could be all sorts of worms living there, and something that looks like stones, only SMART. After all, intelligence doesn't have a fixed form. And regarding communication with hypothetical "neighbors" - it's unlikely that two different minds would be able to understand each other... And in general, they would probably be scared of us, and we of them:))))
