Trees and crabs and birds appeared very recently in the timeline of life on Earth and will probably get extinct eons before shrimp or tardigrades know what happened.

Life is likely plentiful in the Universe. Earth-like life is almost certainly unique.

When I said "what happened here" I didn't mean humans, I was thinking more like "chemical reactions that evolve as energy is applied" kind of thing.
