Why Do Prime Numbers Pop Up Everywhere?

Prime numbers are like the building blocks of all numbers. They can’t be divided evenly by any other number except 1 and themselves, just like how bricks cannot be split into smaller whole bricks. Think of them as special Lego pieces, you can use them to build every other number! If you have a big pile of Legos and you want to know what they are made of, prime numbers help you figure that out.
