They were hunters and gatherers so they moved to get food.
Hunters and gatherers moved from place to place in search of food resources. They relied on hunting animals and gathering plants, and as these resources became scarce or depleted in one area, they would move to new areas where resources were more abundant. This nomadic lifestyle allowed them to adapt to changing environments and sustain their basic needs for survival.
