It Moves? It Moves!

Stone Age. The caveman goes out hunting. Escaping from a wild animal, he throws a stone axe at it. Then he drags the animal's body back to his cave, where he plays a wooden flute. While the man was walking, a ball falls from the sky, and he gets the idea to build a machine in his head. At first it was just a cart. Time flies quickly, and the man finds himself in the 20th century, where he transforms the cart into a car and tests it.
