From Smithsonian:

The first wheels were not used for transportation.

Evidence indicates they were created to serve as potter’s wheels around 3500 B.C. in Mesopotamia—300 years before someone figured out to use them for chariots.

The ancient Greeks invented Western philosophy…and the wheelbarrow.

Researchers believe that the wheelbarrow first appeared in classical Greece, sometime between the sixth and fourth centuries B.C., then sprung up in China four centuries later and ended up in medieval Europe, perhaps by way of Byzantium or the Islamic world. Although wheelbarrows were expensive to purchase, they could pay for themselves in just 3 or 4 days in terms of labor savings.
