> "beauty" as a concept would not exist if we were not here.

This is incorrect - see e.g. http://www.bbc.com/earth/story/20150511-why-are-animals-so-b... or https://www.nytimes.com/2019/01/09/magazine/beauty-evolution...

One of the unattractive human attributes is our self-centered arrogance. And unfortunately, combine with our other traits this results in some pretty bad behaviors that have a terrible impact on other species. The question of whether the planet would be better off without humans is not so obviously answered in the negative.

But arrogance lifted to these levels would probably not exist if we weren't here.
