Yes, like trying to explain color to someone blind from birth. No rational way to do that, right?
No. There is no way that I know of explaining the color blue to someone born blind. You can explain the electromagnetic scale and the existence of wavelengths, but I doubt that that will help him understand color. There are, however, billions of people that have SEEN the color blue, so you have facts to support that the color blue does exist. If everyone was blind, then no one would experience the color blue or that such a thing existed. When something is based entirely upon a personal experience, it is not in the realm of reasonable debate. That does not make the experience false, but you cannot argue with feelings. You can only recognize that certain feelings exist.
