Simultaneity, why einstein is a liar

How do you detect a lie? You detect a lie by being TRUTHFUL. If you are truthful, a lie will always confuse you, and the liar will do everything necessary to make the lie truthful in order to undo your confusion. This is where the liar is caught because you know that his truth can never be your truth. The reason why the liar's truth cannot be the real truth is because there is no harmony in a lie. So, if you are lied to, it means you are also a liar and the person with the better lie always wins.
