I like the idea that when we start, the only thing that exists is space stuff (the sun, moon, stars, etc) and one barren rock, which is literally just rock. 

I would point out that this RP started out with a built-in origin story for humans, and then someone made another origin for humans in their backstory, which is a part of that confusion about that missing time. 

If you want, I will be glad to play a nature god and go around and populate the world with normal (and not-so normal) nature stuff.
