When Moses led the Israelites across the desert, God provided them with food in the form of sweet, yellowish wafers that seemed to magically appear on the ground before dawn each day. No more than one day's worth could be gathered except the day before the Sabbath, when they would gather double so they didn't have to work on the Sabbath. Any excess gathered would be spoiled and riddled with vermin a single day after being gathered. When the Israelites first witnessed the phenomenon, they called it by the name we all (should) know today, manna. The literal meaning of manna being, "What is it?" Well, their question has been answered. While I cannot find a full article on it (only brief mention in a few dictionaries and other references), it has been brought to my attention, by my pastor, that this miracle food still exists today. In certain regions of desert, the yellowish wafers still appear on the ground every morning and still will not keep for more than a single day, and they still taste like honey wafers. Bedouine nomads still eat this food to this very day, as it is rich in carbohydrates and provides a steady source of energy. This miracle food, however, now has a perfectly good explanation. You see, insects in the desert often live off of sucking sap from the trees. This sap is quite low in nutrients, but high in sugar, so the insects consume a LOT of extra sugar to get the appropriate nutrients. Well, they don't burn this sugar, so instead, they excrete it. These excretions eventually dry into yellowish wafers. Since the insects are nocturnal, these wafers often seem to just appear out of thin air at dawn. This still fails to address why the manna somehow lasted through the Sabbath when it never lasted more than a day otherwise, but I still find it amazing how science continues to prove the Bible.
