In this case the “scaffolding” was the rock that has been eroded away to leave the arch. It is possible for natural processes to mimic designed processes. That is where Behe’s Irreducible Complexity came to grief.
Since God is the architect behind nature, how do you know things like that arch were not specifically designed by Him to remind us that He knew about arches before we did?
