Some condensation between 2 window panes is hardly a miracle. It's science. If you know even a little bit about air flow, you'd see why the fact that it's condensation and mineral deposits is critical in dis-proving the "miracle".It probably is - you didn't read - It is what it looks like not what it is made of - I wish I had taken the time to go look. A little miracle once in awhile can help through the rough times.
I've seen it myself, I work about a mile away or so. Why is this window different from the old fashioned "Rorschach Test"? People look at clouds every day and see all kinds of shapes.
I'm not really trying to take the wind out of people's sails. But, we've been given the gifts of logic and reason... why do people not use them?
You say, "a little miracle once in a while can help in troubled times." Perhaps, but isn't it a let-down when the alleged "miracle" is really just worn out old glass?
Now, if there were actually patients in that room, and one after another is mysteriously "healed" of their ailment (whether it be the flu or cancer), THEN maybe, I'll say it's a miracle.
