Okay kiddo, So you know how when you draw a picture or write a story, it's yours and you own it, right? Well, grown-ups also create things like music, movies, and books that are their own and they also own them.
Now, the copyright alliance is like a big group of grown-ups who help protect those people's things. They make sure that nobody copies or uses someone else's things without permission.
Think of it like sharing toys with your friends. You wouldn't want them to take your toy and keep it forever without asking, right? That's kind of what the copyright alliance does for the grown-ups who create things. They help keep their toys safe!
