In 1695, John Woodward's An Essay Toward a Natural History of the Earth viewed the Genesis flood as dissolving rocks and earth into a thick slurry which caught up all living things, and when the waters settled formed strata according to the specific gravity of these materials, including fossils of the organisms. When it was pointed out that lower layers were often less dense and forces that shattered rock would destroy organic remains, he resorted to the explanation that a divine miracle had temporarily suspended gravity.
