Why was finding food so important in the civilizations?

Food , the obvious answer, is very important to the survival of the civilization. It was important for civilizations to find a steady source of food and invest in agriculture rather than hunting because it allowed them to settle down. A few people in the community would be in charge of cultivating the food while others are free to do many other things that meet the needs of the community. By finding a steady source of food and settling down, the civilization is able to progress and become more efficient.
