It is impossible to list all the prime numbers as there are an infinite number of them. The list of prime numbers starts: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, ... Suppose you could list all the prime numbers and have done so - there is no prime number which is not on the list. Multiply them all together and add 1. This number is not divisible by any of the listed prime numbers as there is always a remainder of 1. So either this new number is a prime number, or there is another prime number not listed which will divide into it. Which means that the list was not all the prime numbers; meaning it is impossible to list all the prime numbers.
Prime numbers have no divisibles.
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.
It is impossible to list the infinite number of prime numbers and composite numbers.
That's an infinite list.
