No, you never proved the above claim.

You only thought you did.

First you tried to show that the equation

a^p + b^p = c^p

has no solutions in integers a,b,c,p subject to the

conditions 0 < a <= b < c, p > 2, a < p.

For the sake of argument, let's allow that claim.

Then you attempted to extend to positive rationals a,b,c. To do

that, you scale a,b,c down, dividing each by a positive integer

large enough so the new value of a is less than p. Then you

claim a contradiction since you already showed that a < p is

impossible. But you showed that for positive integer values of

a, not for positive rational values of a, so (barring circular

reasoning) you don't have your claimed contradiction.
