Facts indicate that Fermat had a simpler proof for his last theorem!

1.Fermat really had a simple proof for his last theorem. This is because, at that time, the knowledge of “elliptical curves” used for present proof was not there. So, he never had proof in its present form. The present proof is so complicated to write even in a book having a big margin!2.He never had the wrong proof.His ability of solving his previous tricky puzzles and theorems proves that he used to check very proof perfectly before telling it to his friends. In fact, he proved the above theorem for a particular case of n=4.3.His comment of “the margin of this book is insufficient to write the proof” indicates to me that it must be a geometrical proof, using some triangles.
