The wheel is the most important invention of all time. Before the invention of the wheel, life was totally different. People used horses, camels , donkeys etc to travel from one place to another. It took them days to travel just a few hundred miles. Without the wheel, the world simply wouldn't exist as we know it today. We have cars, bikes, aeroplanes, trains and much more that involve wheels. Without wheels, we wouldn't have any of these inventions. Our life would have been really hard.
