If a kitchen tool breaks, does anyone keep them in their kitchen? Modern man thinks ancient man was a peace loving hippie rather than a killer yet there is little to support that. According to Darwin, man evolved from tribal warfare, yet modern man rejects that as too unseemly to be possible.
We must, however, rule out design for this:
And this:
