No, the question was “How do you [prove that your from the future]?” You laid out a scheme, which you are likely not capable of doing, especially because you missed the bit about the terrifying complexity of that particular proof.

Wiles’ demonstration of Fermat’s simply stated proposition is more than a hundred pages of complex math involving such esoteric concepts as Selmer groups, Hecke algebras, elliptic curves, modular forms, Euler systems and Galois representations. 350 Years Later, Fermat’s Last Theorem Finally Proved
