The primitive men used to get food from hunting animals like deer, sheep, goats, etc. and collecting roots and fruits. They had to face the wild animals to get their food. There were several animals that ran faster so they could not catch them. Animals like deer, sheep, goats, etc. could be easily killed so the primitives used to wander to find them. Moreover, water is necessary for life so they had to find the place with water resources. Thus, the primitive men lived a nomadic life in search of food, water and habitation.
