A round invention helped people move heavy things much more easily.
The wheel lets heavy things roll smoothly along the ground instead of being dragged, which takes way less effort and lets carts, bikes, and wagons move loads far bigger than a person could carry.
A pillow is for resting your head, and a window just lets light and air in — neither one helps move anything at all.
The wheel is considered one of humanity's greatest inventions, and it's still at work today under cars, on bikes, and even spinning your desk chair around.
