I keep on getting questions wrong because I keep on accidently pressing the spacebar.

According to most authorities, the wheel-and-axle combination originated in ancient Mesopotamia during the 5th millennium BC, probably originally in the function of potter's wheels. The wheel's efficient use of input energy must have been quickly understood by its inventors because it was almost immediately set to work in other contexts, most importantly in transport (vehicles) and in foodstuff processing (mill wheels).

The earliest undisputed depiction of a wheeled vehicle (here a wagon -- four wheels, two axles), is on the Bronocice pot, a ca. 4000 BC clay pot excavated in southern Poland.

The wheel reached Europe in the 4th millennium, and India with the Indus Valley Civilization in the 3rd millennium. In China, the wheel is certainly present with the adoption of the chariot in ca. 1200 BC, and Barbieri-Low (2000) argues for earlier Chinese wheeled vehicles, circa 2000 BC. Whether there was an independent "invention of the wheel" in East Asia or whether the concept made its way there after jumping the Himalayan barrier remains an open question.

Although they did not develop the wheel proper, the Olmec and certain other western hemisphere cultures seem to have approached it, as wheel-like worked stones have been found on objects identified as children's toys dating to about 1500 BC. The wheel was apparently unknown in sub-Saharan Africa, Australia, the Pacific Islands and North America until relatively recent contacts with Eurasians.

A spoked wheel on display at The National Museum of Iran, in Tehran. The wheel is dated late second millennium BCE and was excavated at Choqa Zanbil.The invention of the wheel thus falls in the late Neolithic and may be seen in conjunction with the other technological advances that gave rise to the early Bronze Age. Note that this implies the passage of several wheel-less millennia, even after the invention of agriculture. Looking back even further, it is of some interest that although paleoanthropologists now date the emergence of anatomically modern humans to ca. 150,000 years ago, 143,000 of those years were "wheel-less". That people with capacities fully equal to our own walked the earth for so long before conceiving of the wheel may be initially surprising, but populations were extremely small through most of this period and the wheel, which requires an axle and socket to be actually useful, is not so simple a device as it may seem

There now do you understand the joke

You shouldn't offend people like that.

and logically you are an idiot because you have came on this site

look if you don't understand it stop posting like mad on this thread.What you are doing now is fighting about if its funny or not instead of telling espeon how funny it is.

By the way espeon I say again I think it's really funny.
