Which honestly wouldn't be that big of a problem, we've seen crazier stuff in nature before. The issue is that a wheel is a bad and inefficient design for the surface of Earth, which is rough, sloped, covered with stuff, dry, sticky etc. As humans we didn't invent only wheels, we also invented roads to go along with them and leveled rock formations, hills, forests etc to build them. In a fully natural world without roads, wheels are useless.
