Foraging is hard. It takes a long time to find the food and materials needed to feed a village. Foragers often have to walk long distances to get everything they need. Throughout the year, they had to move from place to place as they used up resources or to find follow the seasons. It is not an easy life.
Planting crops and raising livestock meant that people didn't have to move around to follow their food. They could stay in one place, build things to last, and for some, not worry about food every day.
