LOL! and true.
Read several years ago an article that compiled writings of the early French missionaries in the North East. Their descriptions of the tribes of the Iroquois nation were horrific. Eating body parts and children of those captured in front of the captured. They were savages! Later they sold their slaves to the Euros.
Europeans developed a lot of immunity to disease by domesticating and living close to animals (Although close proximity to flea infested rats didn’t turn out to well. (Blame global warming. It was unseasonably cold during those years.)) Native Americans hadn’t domesticated animals yet.
They hadn’t even invented the wheel yet! Although I did read an archeological article years ago that stated a pre-Columbus toy cart with a wheel was unearthed in Mexico. I guess nobody’s light bulb went off.
All in all most really hadn’t got much past the Hunter-Gatherer stage.
In fairness, the natives domesticated (i.e. cross-bred, culling the less desirable strains) a lot of wild plants and turned them into staples. Things like potatoes, chili peppers, corn, beans and squash are available in the form we see today because they were domesticated thousands of years ago by pre-Columbian Native Americans.
