ELI5: Explain Like I'm 5

Anything In Anything

Ok, so let's say you have a toy box full of toys. Inside that toy box, you can find different kinds of toys, like a puzzle, a doll, a ball, and some action figures. Each toy is different, but they are all part of the same toy box. That means that inside the toy box, anything can be found, like all of those toys we talked about.

Now, let's think about a bigger box, like a garage or a closet. Inside that bigger box, you can find lots of things, like tools, clothes, shoes, books, and even more toys. That means that inside that bigger space, anything can be found too, like all of those things we talked about.

So, anything in anything just means that there are lots of different things that can be found inside a space, no matter how big or small that space may be. It's like an exciting treasure hunt where you never know what you might find!
