Why Do Prime Numbers Seem to Pop Up Everywhere?

Prime numbers are like the special ingredients in a recipe, they can’t be divided evenly by any other number except 1 and themselves. Think of them as the ‘atoms’ of all numbers, because every number is made from multiplying prime numbers together. Like how bricks make walls, primes help build math! For example, the number 6 is made from 2 and 3, both are prime numbers.
