Look lets keep in simple..
There are herbivores, carnivores and omnivores..
What have humans be for most of thier history that man has been a “man”?
Hint..Your don’t need weapon to hunt and kill a plant, you don’t need fire to cook a plant, and you don’t need sharp stone knives to skin a plant to wear it as clothing..
Meat eating goes hand in hand with going from a grazing animal, to a weapon caring, fire making, tool using, clothing wearing, man..
It just works out that way
If we had all stay herbivores, we could of all stayed naked, sitting in a tree, eating a banana, and flinging our poop and each other

(Hmmm...That sound a lot like a 60s hippie love in, an Occupy Wall Street demonstration, or a some Democrat Conventions)
There are plenty of carnivores and herbivores on the planet that don’t use fire, clothing, and tools. We have much more the digestive system of a carnivore or omnivore than of an herbivore.
Tell that to the Chimps that have been seen repeatedly hunting and killing small animals, monkeys and even other Chimps, and then eating them. We are omnivores. Insects have also been an important food item in some places. Early hominids probably ate eggs.
Our ancestors were never grazing animals. Our earliest mamalian ancestors were shrew like. I think shrews eat insects and other small mammals, possibly eggs, as well as fruits and seeds. Need to check that out though.
