I think animals are scared of humans because of obvious predatory biological traits, and the sheer size. Most people don't realize humans are large animals.
That wouldn't explain why an animal like a mountain lion would naturally fear us.
It kinda does.
Say that you had some knives and you stumbled across something that looks to be about 3x your height. It looks enormous!
So even if you have weapons, you know it'd probably be hard to take it down for food, and its size makes it a threat, so it'd better to retreat.
I also don't think many animals realize how powerless we are without our weapons. We don't have fur to cushion bites and blows to our bodies, we stand in such a way where are weak bellies are out in the open, and we don't have any weapons that come innately. The only thing we have going from our biology is our mind, and even that's pretty fallible sometimes (Just look around the internet.
)
But all in all, we just look threatening I think.

Humans are not at all predators we're scavangers. We evovled to gather food and take out slow and injured prey. Our sweat and urine contains strong compounds that scare off many other animals making us seem much worse than we actually are. We smell very dangerous. That and the fact that in most the places we inhabit we are aliens to the environment. Our breath also carries a strong scent. Due to the many different types of bacteria that live in our bodies. These bacteria can make a bite from a human bite very dangerous. A bite from a human can slowly poison the blood and kill the victim very slowly and painfully. We were actually pretty dangerous in our large social groups before civilization.
Wow, never thought of that. And I didn't know that our saliva was that dangerous!
