Since you are doing a proof by contradiction and you are assuming

at the start that you have integers x, y, and z that are solutions

of the Fermat equation, then even false statements will be true

(under your assumptions).

We could make a distinction between "derivable" and "true".

Thus, we could say that all of your statements in your proof of

FLT might be derivable, some of which are true, and others false.

This gets back to what several people have requested that you do.

If a statement is true independent of the Fermat counterexample,

then you should separate out such statements as lemmas or

propositions. This would make analysis of your proof easier.

This does not follow at all. There are many true statements in

mathematics that do not have simple proofs.

There is no insinuation that your statements are false. In fact,

David Libert has already proved they are true by invoking Wiles

theorem.

It might be reasonable to you, but we are not claiming the statements

are false. We are claiming that you have not derived them.
