>rocks are never going to rearrange themselves if left to sit

I don't understand this statement. What are mountains? What is sand? What is a planet? What is an asteroid? Where do you think rocks came from in the first place? Over substantial periods of time, rocks are always being rearranged whether or not humans interfere.

Perhaps you are drawing a distinction between being rearranged and rearranging themselves, but I don't understand that distinction. If you think that humans rearrange their own brains, I think that is an impossible thing to even define. How can anything act on itself without an intermediary? What kind of evidence is there for it? Without energy input surely you'd agree that no brain can make itself function? So how is a brain different from a waterfall or rocks moved by a river?
