When was the wheel invented?<end_of_turn>
<start_of_turn>model
No one knows when the wheel was invented with complete precision. Archaeological evidence appears to show that the wheel was first used to make pottery in Mesopotamia about 7,000 years ago, during the Neolithic period. Later, it was used to make chariots, and there is a record of its use for this purpose in Sumeria around 3000 BC.<end_of_turn><eos>
