What if I were to tell you that we are all wrong?

Nobody's perception on these topics were correct, and since we cant seem to get over it, we will undoubtedly eventually all die off anyways in one way or another? If I could prove this to you, without a doubt, (hypothetically, of course), why would I bother because it is useless and it is mans nature to want to be right and disregard other concepts because it is not what they originally believed? So informing you of this knowledge would only hasten the process because it becomes a self-fulfilling prophecy...
