There are a few unexplained phenomena in the universe that physicists do little more than shrug their shoulders at. Any of them could be evidence of other life, and there are proposed theories suggesting as much. We can’t prove anything definitively because we’re too limited in how far we can go towards explaining the unexplained, but I’d say there’s an asterisk on “nothing”.
