What are all the different methods to prove something is true?
Obviously we can’t only rely on the scientific theory to explain everything we believe in or that we have experienced. So there are are various ways to explain different events in the history of the world. For instance we can’t prove scientifically the existence of Alexander The Great, we would prove it, however by historical proof. But what is it needed to prove someone historically, forensically, etc.
