What are the four reasons the invention of fire was so important to the caveman?

There were several ways that the controlled use of fire benefited early man :

• He could stay warm in colder climates (and avoid freezing to death)
• He could cook food (and smoke meat and fish to preserve it)
• He could set grass fires to drive prey
• He could frighten away menacing animals (or other humans)
• He could create more types of tools from wood and other materials
• He could live in deeper, safer caves and explore them
