For any ZFC statement we can build a Turing machine that enumerates all proofs in ZFC and halts if and when it finds a proof of the statement. Then we can find a system of Diophantine equations that has an integer solution iff the Turing machine halts.

Can this encoding be done in a more natural way? Like "AND" corresponds to direct product of varieties, "OR" corresponds to disjoint union and if there is a deduction between two statements there is also a map between the corresponding varieties (that takes a roughly similar number of bits to define)?

It probably should be impossible (because the variety corresponding to FLT would be mapping to an awful lot of varieties); I would be interested in a meaningful negative result in this direction.

Translate ZFC statements into systems of Diophantine equations compatibly with geometry
