Evolved intergalactic beings and evolutionary terrestrial beings co-existed in harmony in some past eras. Evolutionary humans gained gradual intellectual growth generation after generation. They applied their intellectual ability to gain terrestrial supremacy.

The evolved beings who did not believe in owning anything pulled the plug and left the place. Evolutionary beings continue to evolve intellectually but degenerate consistently in consciousness.

There’s no coexistence possible now, as there is no room in the human social constitution which is not ownership-based.
