Creatures live in the blackest depth of the sea under thousands of tons of pressure. We cannot really state that our kind of air is the only kind living things cou breathe or that they must have water or a certain climate. Creatures that breathed othe gases or lived in other temperature, however, certainly would not look like us. Are there people anywhere else in the universe? Maybe there are. In our own galaxy, there are billions of stars. Some must have planets with conditions like those on Earth. Somewhere in space, there could be other thinking beings.
