Stop polluting, or the turtle will dive & we'll all drown.

(Hoping fictional paganism is as acceptable as the other kind.)

If I wasn't clear, our belief is that the world is mainly ocean (70%), there is a great turtle swimming in it, & the land we stand on is the turtle's shell. That doesn't affect the lights Raven put in space. Or am I misunderstanding your meaning?

That works for me! But your image also calls Discworld to mind (I couldn't resist).

I've heard of a book called that but haven't read it. A place where flat-earthers fit in?

It's a series set on a flat earth (where there is an oppressive monotheistic religion that insists that the world is a globe) . . . utterly wonderful.
