Dr. Pepper, the reason why I believe that Fermat did have a valid proof is that otherwise how could he have made such a bold statement that one will never find any triplet of integers a,b,c where a^n + b^n = c^n for any integral power n greater than 2. A single counterexample could have disproved his conjecture. A great mathematician would not have left himself open to ridicule by making such a sweeping statement if he did not have an ironclad proof.
