5. Where did all the water come from? According to the Bible story the waters prevailed upon the earth a hundred and fifty days, and covered all the high hills and mountains under the whole heaven. Now mount Ararat itself, on which the Ark eventually rested, is seventeen thousand feet high, and the utmost peaks of Himalaya are nearly twice as high as that; and to cover the whole earth with water to such a tremendous height would require an immense quantity of water; in fact, about eight times as much as is contained in all the rivers, lakes, seas, and oceans of our globe. Whence did all this water come? The Scripture explanation is sadly insufficient; the fountains of the great deep were broken up, and the windows of heaven were opened, and the rain was upon the earth for forty days and forty nights. The writer evidently thought that there were great fountains at the bottom of the sea, capable of supplying water in unlimited quantities from some central reservoir; but science knows nothing whatever about them; nay, science tells us that the internal reservoir, if there be one, must contain not water, but liquid fire. If _this_ great reservoir poured its contents into the sea, the result would be similar to that frightful catastrophe imagined by the Yankee who wished to see Niagara Falls pour into Mount Vesuvius. The supply from that quarter thus failing, we are forced back upon the rain which descended from the windows of heaven, wherever they may be. It rained forty days and forty nights. Forty days and forty nights! Why forty million days and nights of rain would not have sufficed. The writer was evidently in total ignorance of the laws of hydrology. The rain which falls from the clouds originally comes from the waters of the earth, being absorbed into the atmosphere by the process of evaporation. The utmost quantity of water that can thus be held in suspense throughout the entire atmosphere is very small; in fact, if precipitated, it would only cover the ground to the depth of about five inches. After the first precipitation of rain, the process of evaporation would have to be repeated; that is, for every additional descent of rain a proportionate quantity of water would have to be extracted from the rivers, lakes, and seas below. Now, surely every sane man must perceive that this pretty juggle could not add one single drop to the previously existing amount of water, any more than a man could make himself rich by taking money out of one pocket and putting it into another. The fabled man who is reported to have occupied himself with dipping up water from one side of a boat and emptying it over on the other, hoping thereby to bale the ocean dry, must have been the real author of this story of Noah and his wonderful ark.
