Interesting point - population density when such spheres were being manufactured was low. Which leads to the next idea: when population density increased, spheres were no longer manufactured. Why? Something replaced them. Arrowheads?

We can start to unpick the mystery with insights like that.

Kind of makes you wonder if the first arrow heads were formed when someone was trying to make a sphere and struck the rock with flint (or one of the other suitable stones) and accidentally cut themselves on the sharp resulting shard.
