Apparitions from heaven???

[Jehanne]

Why jump unhesitantly to the conclusion it must be a miracle? We have good psychological explanations for why stuff like this happens, whether it's to do with selective attention, misinterpretation, biases, illusions, mass hysteria, etc.

I think a mass of thousands of people (including skeptics) having the same hallucination at the same time is just too much of a coincidence to make much logical sense imho.

You forget (over and over) that some individuals denied that anything supernatural was happening at all!  Some also claimed that the ground, which was soaked from all the rain, also became miraculously dry, as did their clothes.
