eli5 why does air not find an equilibrium on our planet?

I always experience winds on our planet and I know it’s caused by different pressure areas. What causes wind to keep perpetually going and not evening out in mostly an equilibrium with the only changes being caused by moving things such as cars.

The sun heats the air causing it to rise. Rising air pulls in more air behind it. This is the main cause of wind. The planet rotates (which also directly affects wind) so there is constant change between day and night, meaning the same location inevitably heats and cools cyclically. Anytime one part of the atmosphere heats more than another part, it will cause wind so the only way to achieve equilibrium is for the sun to die (pretend it doesn’t destroy earth) and the planet freezes.
