Hi,

You say my synopsis is wrong as a whole? Please, explain.

It also seems you want me to provide a proof... Ok, here it goes.

We say a natural number is prime iff it is greater than 1 and doesn't
have any divisor other than 1 and itself.
By the fundamental theorem of arithmetic, every number greater than 1
has a prime divisor.

Let us suppose that the subset of all prime numbers is finite.
Then the product of all primes plus one, since it doesn't belong to
the subset of all prime numbers (it is greater than any of them) is
not a prime, but it has a prime divisor, since it is greater than 1.
But in fact, it doesn't have any divisor from the list of all primes.
Contradiction.

I keep on believing that the key idea in this proof is the
construction of the number "the product of all primes plus one", and
not the strict application of the rules of logic, which are supposed
to work when applied correctly.

For some other proofs of the infinitude of primes I recommend:

Number Theory. An Introduction via the Distribution of Primes
Benjamin Fine
Gerhard Rosenberger
Birkh=E4user

Cheers.
