Why does everybody assume that this law applies to absolutely everything in existence? It clearly does not; contradictions exist all over the place, most impressively in field of quantum mechanics.
We still accept it because without it no proof, evidence or knowledge is possible. Even saying that the law of non-contradiction is inapplicable assumes that there can be only two cases -applicability and non-applicability - that it has to be one or the other, but not both.
And apparent contradictions in quantum mechanics are not actual contradictions.
