This OP is from someone admittedly ignorant of science. It is not intended to be controversial. I am not raising the issue of whether miracles can happen; I believe they can. I am more curious as to the behavior of nature when a miracle is occurring. Perhaps a concrete example will help:
We are told that on two occasions Jesus multiplied bread. I admit I have always had difficulty imaging such an event--after all, if I were looking at one of the baskets, what would I see? Would the loaves be bubbling and expanding; would there suddenly appear a new loaf. But I also admit that the inability of the imagination to reproduce an event does not make that event impossible. What I am really interested in is the chemistry required for that to take place:
After all, we have something appearing that wasn't there before (new loaves). Loaves are, I assume, made of atoms. That means these atoms had to come from somewhere? Where did they come from? Was there an enormous shift of atoms as some from the ground move through a disciple and ultimately come into alignment with other atoms so that finally we have a new piece of bread?
And yes, I am aware that I probably just exposed my embarrassing deficiency in atoms.
Oh, other miracles are forthcoming
