I actually prefer to be optimistic about things we don't have a clue about. We can be better. The sentient beings that possibly observe us (without leaving a trace) might also see our potential - we may be selfish and conceited, but we can also adapt and take care. It's not one or the other. When I was a child, that fjord where we used to swim gradually turned into a sewer. Now the water is clean, the fish have returned, because it became illegal to just flush waste into the environment. In Japan, I've heard children clean their own classrooms every day. Not sure if it's true, but it could explain why the supporters of Japans national football team clean the stadium after a match, as a tribute. We can learn.
