Without humans there would be no one (as far as we currently know) to appreciate and contemplate the beauty of the universe and planet earth. So it would all be pointless.
Oh? And what does contemplating and appreciating the beauty of universe and planet earth accomplish?
It's us who define the concept of 'accomplishing something'. The universe without humans is pointless, because it's us (that we know so far) who say what has a point at what hasn't.
Sounds tautological. Universe without humans is meaningless (in human terms) because we define what meaning is (in human terms).
It does, but then again we don't know of any other source of meaning than ourselves.
