Rag Tag Prompt; antediluvian. And you say you use it all the time? Holy Moly. What a way to divide time; before and after the biblical flood.
Of course there are a lot of flood stories in many cultures which sort of proves it happened. Melting ice caps, perhaps? Who knows….. it was antediluvian.

I encourage everyone on Turtle Island (North America) to find when and where their local Powwow is and GO.
