Humans dont fight animals only run
If humans get attacked by an animal they never fight back instead try to run. Sometimes there's no chance of running but the human still doesnt fight back. I actually think in many cases a human actually has a chance of killing a attacking animal with their bare hands. For example if a dog attacks a grown man he could lift the dog in the air and slam it. Or if he could get around the dogs neck he could strangle it. But humans rarely fight back against animals and instead submit to their fate. Human males are actually quite large and can generate alot of force with their fists and legs.
