They say that in order for something to exist, it must have a beginning and an end.
This is obviously an idea from before the invention of the wheel, because any semi-intelligent person today can look at a circle and say with confidence that there is no "Start Here" point*, nor is there any sort of definite end. Based on this observation, we must begin to question the actual existence of wheels. Maybe they never were invented at all, which would make reinventing them seem quite necessary since the current model only exists due to a crude technicality**.
*Some will argue that there is an infinite number of starting points on a circle, which may be true, but it's also the exact same thing as there being none at all, because a non-existent starting point is still a starting point - just a really, really tiny one. You know, infinitely tiny.
**That is, cars aren't moving along on concrete bricks.
Then again, perhaps theoretical existence is all it takes...
