What was the first vehicle with wheels?

The first vehicle with wheels was probably a sled. Sleds have been used for thousands of years to transport people and goods over snow and ice. The earliest sleds were made from animal bones or wood, and they were pulled by humans or animals. Over time, sleds evolved to become more sophisticated, and they were eventually used for transportation on land as well as on snow and ice. The first wheeled vehicles were probably developed by the ancient Sumerians in Mesopotamia around 3500 BC. These early wheeled vehicles were used for transportation of goods, and they were pulled by oxen or donkeys.
