Hey I love (and defend) crypto but ultimately it relies on (sometimes standard) assumptions like the one-way hardness of discrete logarithms. Symmetric systems hardly have underlying information theoretic garuntees - usually symmetric constructs are based on reductions under random oracle models (which have has its own methodological problems). Furthermore implementations are hardly the same as mathematical constructs, which gives rise to side channels.
These are not controversial views - they are common knowledge among cryptographers.
It is thus an injustice to knock Elephant on 'provability' grounds. The papers for Elephant (and Lion before it) follow standards for peer reviewed work in cryptography.
It is a shame you will not reply to any of the examples in the remainder of the comment.
But other HN readers will see them.
