In the beginning, humans ate horses. Some Neanderthals still do. About 25,000 years passed and one day a human—I personally think it was a woman—heard a voice in her head that she didn’t recognize. It was a deep soft voice, like Barry White, only 5,956 years too soon. The human looked for the cause of the voice and saw a horse—I personally think it was a white horse. The human was a bit unsettled, so the horse took a deep breath and exhaled, and sure enough, the human mimicked him.
The horse thought there might be a chance that this frail human had a soul, so he offered his help.
And that’s how humans domesticated the horse.
