Why did the Aztecs practice ritual human sacrifice on such a massive scale?

Imagine the sun is a giant, glowing vampire baby. If it doesn't get its daily bottle of fresh blood, it throws a tantrum and the whole world ends.

The Aztecs believed the gods sacrificed themselves to create the universe, so humans owed them a massive, bloody cosmic debt. Think of it as the worst credit card interest rate ever.

To keep the sun moving and the crops growing, they paid this debt with human hearts. It was just their very messy, extreme version of paying the utility bill to keep the lights on!

How exactly did the gods sacrifice themselves to create the universe?

Before humans were around to foot the bill, the gods held a divine bonfire party to kickstart the world. The catch? Someone had to jump in to become the sun.

While the rich, handsome gods hesitated, a sickly, pimple-covered deity named Nanahuatzin just threw himself straight into the roaring flames. He instantly transformed into a blazing sun.

But he refused to move across the sky until the other gods coughed up some blood too. So, the rest of the pantheon reluctantly slaughtered themselves just to get the solar system's gears turning. Talk about a toxic workplace culture.

What happened to the rich, handsome gods who hesitated to jump into the fire?

The main wealthy coward was a flashy deity named Tecuciztecatl. After watching the sickly underdog steal the spotlight, his bruised ego finally pushed him to jump into the leftover ashes.

He popped out as a second sun, making the sky blindingly hot. The other gods, annoyed by this obnoxious double-glare, decided to literally throw a rabbit right at his glowing face to dim his shine.

That humiliating slap turned him into the moon. So, every time you look up at night, you are basically staring at a bruised celestial ego with a permanent rabbit shaped black eye.

Why did the gods specifically choose to throw a rabbit at his face to dim his light?

Mesoamerican stargazers didn't look up at the night sky and see a romantic "man in the moon." They saw a giant, glowing rabbit trapped in the craters.

To explain this astronomical quirk, Aztec storytellers needed a brutally logical origin story. What better way to explain a rabbit-shaped shadow than a literal rabbit being weaponized by annoyed deities?

The gods didn't carefully select a sacred emblem. They just grabbed the nearest heavy, aerodynamic mammal during a divine temper tantrum and pitched it like a celestial fastball. It was purely a crime of convenience.

Why did Mesoamerican stargazers see a rabbit in the moon's craters while other cultures see a man?

Human brains are basically paranoid pattern-recognition machines. We evolved to instantly spot shapes in the shadows so we wouldn't get eaten by lurking predators.

When we stare at the random, dead impact craters on the moon, our survival instincts misfire. We desperately try to connect the dots into something familiar.

Since Mesoamericans were surrounded by local wildlife, their brains auto-filled those dark lunar shadows into a rabbit. Meanwhile, Europeans hallucinated a human face. It is just our collective, ancient anxiety projecting cosmic Rorschach tests onto a giant space rock.
