Therefore, this allowed other people, non-farmers, to do other things such as make tools, craft pottery, and build homes. Farming and food surpluses led to the division of labor.

As the population of villages expanded, so did the needs of the people. Things got complicated. But, civilization is just that - advanced, complex societies. And without farming, they would not exist.
