I found this article on the dot coms this morning. It implies all non-terrestrials are "extra", but it seems that Beings of human and Human Beings, of which there is a distinct difference, are the ones who are most frequently "extra".
There is even an article there on hunting "intelligent aliens", as if intelligent non-terrestrials could possibly be hunted.
Have you reached out to your accessible non-terrestrial(s) lately?
Perhaps the book of non-terrestrial etiquette would be best written by a non-terrestrial? Please, share with me what your opinions are on this matter.
