ELI5: Why do we need the Moon?
gpt
The moon stabilizes Earth's axis so that it doesn't wobble too much. It essentially acts as a weight, pulling on the Earth and keeping it on a fairly uniform rotation. This means that we have regular and consistent seasons and temperatures, which allow for agriculture, modern civilization, and all that fun stuff. Possibly even life itself because it's kind of hard to grow in a region when you can't predict what environment you'll be in within a year.
