How are you calling 1914 wrong without replacing it with something that can be right?
Fallacy: argument from ignorance, non sequitur. There isn’t anything ‘right’ to replace it with because the entire premise is faulty. Aside from that, it isn’t necessary to know an exact answer for something to know that a particular answer is wrong. For example, if I say the square root of 7636546745875348734744763673674 is 3, it isn’t necessary to know the correct answer to know that it isn’t 3.
