(Genesis 6–9) describes a worldwide flood (the Noachian Flood) covering even the highest
mountains of the earth and the construction of a huge boat (a rectangular box-like craft) that transported animals, at least two of a kind of all land animals on the earth. Bible says that the rains that created the Noachian Flood lasted for 40 days (Genesis 7:17), that the waters prevailed on the earth for 150 days (Genesis 7:24), and after these 150 days the waters gradually receded from the earth so that by the seventh month and the seventeenth day, Noah’s Ark came to rest upon the mountains of Ararat (Genesis 8:4). A year plus two
months and twenty-seven days later the earth was dry enough so that
Noah,his family,and the load of animals could disembark from the Ark
(Genesis 8:14). Because this flood was intended by God to destroy all flesh on earth
(Genesis 6:13) and because sedimentary rocks on all continents
contain fossils that supposedly represent the “destroyed flesh of all
life,” it might be thought that the Bible story, describing a whole earth flood, was true. However, interlayered with these fossil-bearing sedimentary rocks on all continents are layers of evaporite rock salt (sodium chloride), gypsum
(hydrated calcium sulfate), anhydrite (calcium sulfate), and various
potash and magnesium salts, which are associated with red beds
(shales) containing fossilized mud cracks (Schreiber and others 2007).
Many of these mineral compounds and red beds have combined thicknesses on different continents of more than one kilometer (~3,281 feet) (Collins 2006). The
red beds are red because they contain red hematite (iron oxide) which formed from magnetite gr
ains. Raindrop prints occur in many places around the world which could not have been formed or preserved if the muds (now in
shales) containing these prints were deposited under water
during Noah’s flood. (Senter 2011; Hill et al. 2016) Nests of dinosaur eggs are found in several places around the world, and it is illogical that dinosaurs could have had enough time to create these nests and lay their eggs while they were
fleeing from rising waters to reach higher ground. (Senter
2011; Hill et al. 2016)
a marine sea was once present and to disappear when the sea became
completely dry. Therefore, one could expect these evaporites to
be at the top of the supposed Noachian Flood deposits when the
water supposedly receded and the land dried out, but certainly not in
different levels in between older and younger fossiliferous “Flood
deposits”. We read in the Bible that there is only one time in which the Flood
waters are said to recede and leave the earth dry. That is, no multiple
worldwide climatic conditions are described in which flooding, then
drying to a dry earth, more flooding, more drying to a dry earth, in
repeated cycles that occur over and over again in that Flood year. On
that basis, it is logical that all the kinds of evaporite deposits and red beds in many different levels in the supposed Noachian Flood deposits could form only in local climates with desert drying-conditions and could not possibly have formed all at the same time — a time when flood covered the whole earth for more than one year (Collins 2006). On that basis, the Noachian Flood story cannot describe a whole-earth flood, but it could only represent a
large regional flood.
