We don't know if we are the only life in the universe. Life could look very different in other places. Life could be something like bacteria in places like an underground liquid ocean somewhere. Life could be a more sentient being that has totally diffrent chemical systems to live in than us. I saw a video talking about how entire galaxy, world's, and even civilizations could be made up of dark energy. Dark energy can not interact with anything made of regular energy. We would not be able to see/derect/ interact with anything made of dark energy. Long story short, there could be life everywhere but not in forms we recognize or can interact with.
