Answer 2

Our ancestors used to have natural predators -- lions, tigers, bears and all other carnivorous creatures that they met when humans still lived in caves.

Thankfully, human beings were smart enough to counter these predators with their weaponry. Eventually, humans established territories and civilizations that kept their predators away. Some animals, such as dogs and cats, were domesticated and are no longer our predators.

The only predators humans have now are each other.
