The annoying 0

A prime number has exactly positive two divisors: 1 and itself. But $\frac 00$ is undefined. Hence 0 is not prime.

For an integer to be prime it must be $>1$ . But $0\ngtr1$ , so $0$ cannot be prime.

In order to be prime, zero would have to have two divisors, but it has infinitely many! Is antiprime
