Humans really are badass. Not only did they kill massive Wooly Mammoths with spears, they would also have had to defend the kill against such predators/scavengers as the bears, wolves, lions, etc.
What’s next? We can only imagine: eating tiny insect purée from a chewing-machine in the comfort of our shared condo-room, with the A/C at full power
We don't actually know how they hunted the mammoths.
