Before the invention of the wheel, the only means of transportation was walking. For transporting goods, people used animals like donkeys, horses, mules, elephants, oxen, sled dogs, and even bison. Boats were also used as a means of transportation on water. The earliest boats were simple logs of wood with a hollow cavity.
The oldest wheel was discovered in Mesopotamia, and is believed to be over 5,500 years old. Fixed wheels for carts were invented around 3500 BC, according to some historians. After the invention of the wheel, man started using animals to pull vehicles that moved on wheels, and thus, bullock carts and chariots came into existence. Till the 19th century, most forms of transport used only animals.

A Prayer for Confidence When Uncertainty, Insecurity, or Timidity Hits - Your Daily Prayer - June 3
