The figures looked more or less human. And they were engaged in religion. You could tell by the knives (it’s not murder if you do it for a god).
—(Terry Pratchett, Small Gods)
There is a race of beings that have endless lifespans. Because of their eternal existence, the only forms of time which they understand are being and non-being. They do not understand words or ideas such as past, future, present, yesterday, today, tommorow, then, now, when, until, ect. They do understand yes, no, live, die, on, off, there, not there, existent, non-existent, ect.
