The concept of a "planet" has been around for millennia, and the moon (and later Jupiter's Galilean moons) have never been considered planets.
Right, and if there's one thing I know, it's that the things that people thought millennia ago should never ever be challenged, ever. Tradition is sacrosanct and if they thought it was true 2,000 years ago, then damnit it's still true today. This is why everyone still prays to Zeus up there on Mt. Olympus, and why we always will. It's also why I know that the heliocentric model is bullshit, because for millennia we knew that the sun goes around the Earth. It's just common sense.
I also know that the so-called "theory" about micro-organisms is bullshit, they don't exist. If they did, we would have known about them millennia ago. Everyone knows that if you make a hole in a brick, put some sweet basil in it, cover that brick with another brick, and leave the bricks out in the sun, then that basil is going to transform into scorpions. Everyone knows that. It's how the world works.
Oh, what's that, you don't want scorpions, you want mice? Fine, have it your way. Take a dirty shirt and stuff it into a vessel containing a little corn. The ferment proceeding from the dirty shirt will mix with the odor from the corn, and in about three weeks it will transmute the grain to full-grown mice of both sexes. Boom, now you can feed your snake.
I don't want to know how you got that snake though, those things are just unnatural.
