One opinion says that hunting was invented by the people who lived
back at the beginning of people. I think it goes back even farther than
that.
Every living thing that can move around goes hunting for things to eat,
and there were a huge number of living things that could move around,
long before people came along. Like dinosaurs, bats, cockroaches etc.
So I don't think you can say that hunting was ever invented. It was just
something that living things just naturally always did, like breathing.
