We (humans in general) have not had to hunt animals unarmed for more than a hundred thousand years. We had bows, spears, spear throwers

Before that, before we were homo sapiens, we probably scavenged other animals’ kills, smashing the animal’s skull in with a rock to get at the brain

We know humans were predators by examining the bones of old skeletons. You can tell by the isotopes the bones are made of what the person ate - plants, animals, seaweed, fish, shellfish

But the main thing that makes me certain we are made to eat meat is that you can die from eating too much sugar, you can’t eat too much meat or fat your body tells you to stop. The current epidemic of diabetes shows that there is no stop signal for sugar
