Why do we pay money in exchange for goods?

Alright, imagine money is like special shiny stickers! These stickers are super magical because everyone agrees they can be swapped for things we want or need.

Let's pretend you really want a yummy ice cream. The ice cream shop doesn't want toys or crayons, but they love these shiny sticker-money! So, you give them some of your sticker-money, and they give you ice cream. It's like trading, but with something everyone wants.

This way, you don't have to carry lots of toys around to trade – just your sticker-money! It makes getting things a lot easier and fun, like a magical trade game everyone plays.
