A New Word

I would like to propose a new word for the English language, not my first by any measure.

We use the word "alien" to refer to people from a foreign country or beings from a different world.

I would like to propose the noun "athien" to refer to anybody living in a world without God. That can include atheists living in a world of believers since atheists claim, no matter what the claims of believers, that there is no God, no Allah, no divine creator, even no intelligent design. For the athien, there is no God in the world in which they live.
