ELI5: Why can't you close finder on macs?
gpt
Because the desktop is part of Finder, so if you were to actually quit out of Finder, you would no longer have an interface with which to access anything in OS X. 

Imagine a real, physical desk with paper files and folders sitting on top of it. Finder is not just the files and folders on the desk, but it's also the desk itself. Now imagine two guys coming in picking up your desk with all the files and folders on it and walking out with it. You're sitting in your chair looking at the empty, dusty space where your desk used to be. That's what quitting Finder would be like. Now go outside and take a deep breath. Look up at the sky. Go for a run. What the fuck else are you going to do? They took your desk.
