I heard that once in a bible class and it's stuck with me ever since. And imo it beautifully encapsulates humanity's trends and fads.
Language is an ever-evolving thing, but at the same time, how many variations of something can be made before we've made all of them? Humanity has been around for thousands of years; I find it hard to believe that just about any word we could come up with is actually brand new and no other human has heard it before.
