finally someone who gets it. Congratulations, dawntodaylight.
We're all wrong, because knowing all that there is to know is not possible. But what remains within our purview is recognising and ultimately knowing what is not possible. If someone tells us that something is possible, believes it with all his/her heart and soul as a matter of fact, but cannot furnish even the tiniest, most miniscule fragment of real proof, then we can only be left with the understanding that it is in all probability not the truth.
