There are many unanswered questions pertaining to human history. What was the first language? Why do we feel emotions? Exactly where did the first human come from? Yet one question rules over the rest, hovering over the heads of puzzled scientists. Why do we drink milk? Or, more specifically, who in the hell thought to pull on a pink dangling thing underneath a cow, see white stuff come out, and then DRINK IT? Sure, whoever this individual was, their logic wasn’t completely flawed, as humans spend the first year of their life drinking milk. But it could have gone very poorly.
Most likely the first Milkman was in fact a male, as men tend to have more dumb ideas than women. So this person happened to luck out by choosing a cow. It’s possible that he could have stumbled upon a cat and decided to milk it, which would likely have yielded fruitless yet harmless results. But say he had decided to milk a horse, or even worse, an alligator. The future of humans would have been drastically different. No milk means no Marie Antoinette saying “let them eat cake.” No milk means a race of people who don’t exceed 4 feet. No milk means no mid-class gastrointestinal issues from Aaron.
Thankfully, the Milkman chose a cow. Now, imagine if you lived in a small community of 30 or so people, who may or may not have had language, and largely depended upon each other for resources. You have been living tranquilly in a temperate valley for the past 20 years, and in two years you will be old and die. Suddenly, Thag, the town fool rushes into your village holding a handful of white liquid, some of which appears to be dripping down his beard, a wild and crazed look in his eyes. Of course, you might assume the worst. But he tells you to drink it too, for it tastes good; and lo, it is, and rejoice! for Milk has been discovered. Soon, there will be cookies, ice cream, Got Milk? posters, and of course, yogurt. A revolutionary discovery has been made, and the world may never be the same again. So thank you, Milkperson, for not trying to milk an Emu. We appreciate it.
