Proof of Fermat's Last Theorem

Sorry about this.

I was messing about with Fermat's Last Theorem. Could you quickly look at my "proof" and spot the mistake?

I'm so surprised that an "aspiring mathematician" failed to solve this in $3 \frac14$ hours.

I imagine that (almost) everything simple has been tried and tested to death.

There is (almost) certainly no short proof of FLT. If there were, and Fermat knew of it, he would have given it instead of the more limited proof that he did write down.

Didn't want to clog the forum up with a new thread to ask this.

Does Andrew Wiles, or anyone for that matter, fully understand his proof of Fermat? Supposedly it uses results from outside the specialties of Wiles.

There is, in fact, no evidence that Fermat actually had a "simple proof" and considerable evidence that he didn't. Although the note in the margin of a book was not found until after his death, he certainly had the book and was working on problems related to the book before he published proofs for n= 3 and n= 5- thus it is likely that he wrote the note before publishing those proofs. If he had a "simple proof" for all n> 2, he would have published that proof rather than separate proof for n= 3 and n= 5. What happened was what happens to all mathematicians at some time- he thought he had a proof but, on deeper consideration, discovered it did not work.
