Answer:
Theories suggest that Australian Aborigines arrived in Australia about 40,000 years ago. These early settlers lived in different groups, or tribes, and spoke different languages. Within tribes, many Aborigines lived in smaller groups or clans. Family was extremely important to many Aboriginal Australians, as it provided the necessary components for survival: food, shelter, and support. They were nomadic hunter-gatherers and used spears, nets, and boomerangs to hunt. They set off controlled burns in the forest to promote vegetation growth. Aboriginal Australian religions often centered around animism and ancestor worship.
