I used to work cash at a grocery store and on very boring evenings we found something to amuse ourselves - made fun of the tabloids. There is this one that's printed in black and white (totally can't remember the name). I've seen Satan burst out of hell, appear in the sky over the vatican, and several other key religious spots. If it wasn't the same picture (used loosely) that they used EVERYTIME maybe they would have succeeded in convincing someone of it.... or maybe not. It's the same tabloid that runs all those stories about Batboy. Some people will always be gullible enough to believe whatever they hear, but hey, it keeps the tabloids in print!
If one opts for belief in revelation, reason can no longer declare that such belief is untenable. If on the other hand, one opts for disbelief, there is nothing reason can do to prove the validity of revelation.
