Like why planet? Why sphere? Why is there a solar system? Why system instead of no system? How did entropy create anti-entropy agents? Bees, humans, anything that builds non-random structures?
Sorry if this is a bad question, it just popped into my head and it won’t go away.

The Universe gets more messy with time — but part of it can get in order, as long as another part gets *even more* disordered.
Rack up a set of pool balls (and block the pockets), and break them with the cue. Call the energy you used to hit the cue, **X**. The question: can you return the balls back to the rack?
Of course you can. Can you come up with a way to do it that, even if you do it a whole bunch of times, uses *less* energy than **X**?
The ELI5 answer is “no”. That’s why cars break down, but people have to fix them. Rooms get messy, and people need to clean them. You have to mess up the *whole universe* more, to tidy up your corner a little less.
