Indeed, the truth exists irrespective of whether lies exist or not. The truth is what is true, reality itself. Put one apple in a basket, you have one apple in a basket. add another, and that's 1+1 apple, 2 apples. That is truth. It cannot be disputed, and no lie can change that reality. Sure, a lie can distort, obscure, and misrepresent the truth, but the truth remains beneath those lies.
