I think this important historic phase, was so important, because it paved the way for modern civilization. Before Neolithic, hunting and gathering were the primary forms of sustenance.

With the cultivation of foods like wheat and grains, food storage also made it easier for people to travel long distance. The animals carrying food and equipment longer distances than man could previously go.
