As far as the loaves and fishes miracle goes, It is my understanding that there was a problem with a croud that had followed Jesus into the wilderness. Out of this crowd, only a young boy had had the forethought to bring lunch. By the time the disciples had finished passing around the food, there was enough levt over to fill twelve baskets, as is to show that it was, indeed, a miracle. How this could come from people just sharing with each other is beyond me. It wasn't a pot-luck dinner, these people were walking in the wilderness.
