Because while 1 is not composite because it cannot be divided by anything other than 1, 1 cannot be prime either. A Prime number by definition is a number that cannot be defined by anything other than 1 and itself. However, 1 is, in fact, 1 and is only divisible by 1 (which is itself). Because of this paradox and the breaking of the technicality of the rule, 1 is simply considered not prime or composite in order to not create confusion.
