The 2 most important events in all of history were the invention of beer and the invention of the wheel. The wheel was invented to get man to the beer. These were the foundation of modern civilization. Once beer was discovered, it required grain and that was the beginning of agriculture. Neither the glass bottle nor aluminum can were invented yet, so while our early human ancestors were sitting around waiting for them to be invented, they just stayed close to the brewery. Thatís how villages were formed.
