supplementary....Objections to a Total Noachian Flood.
A global flood would have produce evidence contrary to the evidence we see.
How do you explain the relative ages of mountains? For example, why weren't the Sierra Nevadas eroded as much as the Appalachians during the Flood?
Why is there no evidence of a flood in ice core series? Ice cores from Greenland have been dated back more than 40,000 years by counting annual layers. [Johnsen et al, 1992,; Alley et al, 1993] A worldwide flood would be expected to leave a layer of sediments, noticeable changes in salinity and oxygen isotope ratios, fractures from buoyancy and thermal stresses, a hiatus in trapped air bubbles, and probably other evidence. Why doesn't such evidence show up?
How are the polar ice caps even possible? Such a mass of water as the Flood would have provided sufficient buoyancy to float the polar caps off their beds and break them up. They wouldn't regrow quickly. In fact, the Greenland ice cap would not regrow under modern (last 10 ky) climatic conditions.
Why did the Flood not leave traces on the sea floors? A year long flood should be recognizable in sea bottom cores by (1) an uncharacteristic amount of terrestrial detritus, (2) different grain size distributions in the sediment, (3) a shift in oxygen isotope ratios (rain has a different isotopic composition from seawater), (4) a massive extinction, and (n) other characters. Why do none of these show up?
Why is there no evidence of a flood in tree ring dating? Tree ring records go back more than 10,000 years, with no evidence of a catastrophe during that time. [Becker & Kromer, 1993; Becker et al, 1991; Stuiver et al, 1986]
Problems with a Global Flood, 2nd edition
Also - This person claims some expertise. Whether or no, they are arguments I have read before, so the science supports .
1. Angular unconformities – Angular unconformities are where sediments are laid down in layers, then tilted and eroded, then new sediments are deposited on top. How does a global flood simultaneously deposit, tilt, and erode in the same exact place?
2. Radiometric dating – All common forms of radiometric dating, including C14, K-Ar, Ar-Ar, Rb-Sr, Th-Pb, U-Pb, and fission track. The dates derived from these diverse methods, when properly interpreted rather than intentionally misapplied, show that all but the very most recent deposits in the geologic column is vastly older than any postulated flood.
3. Fossil Sorting – The sorting of fossils in the geologic record is consistent with evolution and geology across all formations worldwide. There are basically no fossils of dinosaurs found with modern mammals, even when such dinosaurs could fly. There are no flowering plants in the Cambrian, no grasses, no mammals, and no birds. The overall sorting does not show any evidence consistent with a flood or settling in water.
4. Varves – How does one create 20 million annual layers, each layer which would have taken at least a month to settle due to hydrodynamics as is observed in the Green River Formation? How does one explain seasonal of pollen grains found in the layers?
5. Sedimentation rates – Why would there be Precambrian rocks below ones feet in the Canadian Shield area, yet the entire geologic column in the Williston Basin in North Dakota? Why would a global flood scour down to the Precambrian in one place yet at the same time deposit tens of thousands of feet of sediment in another when it is exactly the same process? Giant post-pyramid ice ages are not an explanation as there is no written record or other evidence of increased historical glaciation to the extent needed to scour the Canadian Shield down in the last 4500 years, not to mention such Precambrian rocks elsewhere on Earth like South Africa.
6. Lava layers with ancient soils between flows – How could lava forms which only exist with a land surface interface create interbedded deposits with paleosoils?
7. Ice sheets – Ice caps can’t reform in the time allotted since any global flood of 4500 years ago.
8. Ice core data with correlated known volcanic events – Ice cores can be dated back by multiple methods nearly a million years, yet show no evidence of a global flood.
9. Ocean core data – Ocean cores would show unsorted piles of terrestrial life and different distributions in grain sizes than observed. They would also show little difference in thickness between the mid Atlantic ridge and near subduction zones, which is not what is observed.
10. Paleomagnetism – Because the Earth’s magnetic field has reversed polarity and has wandered over the globe in the past, certain igneous rocks show such preferred magnetic orientations when sufficiently cooled. By mapping these directions and reversals, which correlate with radioisotope dating and stratigraphy, it is easily shown that the vast majority of seafloor sediments, along with most volcanic rock, are way too old to have been deposited by any flood. In fact such measurements are one of the great evidences for plate tectonics, which alone invalidate a global flood.
11. Volcanism – According to ‘flood geology’ every igneous rock layer that overlays sedimentary rock would have to be less than 4500 years old. Yet, historical records indicate this tremendous amount of simultaneous volcanic activity could not have occurred in recent times because someone would have noticed, becoming extinct and all when the atmosphere becomes unbreathable. Such a position directly contradicts the existence of the Deccan Traps which are up to 2 km thick and 500,000 square km in extent, yet supposedly erupted in India despite any historic evidence, after such a flood.
12. Ore deposit formation rates – Most ore deposits require a longer period of time to separate their constituent elements and then cool to create an economically viable source of minerals.
13. Evaporites – The existence of evaporate deposits thousands of feet thick are incompatible with any global flood as they are formed through evaporation rather than through the addition of fresh water.
14. Carbonates – The huge amount of CO2 in the atmosphere prior to being locked into carbonate rock would have made the planet resemble Venus. There would have been no life to drown.
15. Microfossil deposits - Thick deposits of microfossils in limestone, diatomaceous chert, and chalk that could not settle to such a degree of thickness in the time allotted for any global flood.
16. Thick deposits of sand - Sand is the result of weathering and working of formally solid formations, requiring long long times to form and accumulate.
17. Aeolian sand deposits – Wind deposited sandstone is found above and below water deposited limestone. One example is the Cococino formation which is both overlain and overlies limestone.
18. Overthrust formations – the time and pressure required to cause overthrust formations is far greater than can occur in any post-flood historic time.
19. Formation of geologic features such as mountains and valleys – How did something like the Himalaya Mountains form without anyone noticing all those earthquakes? How were valleys cut between such mountains in less than 4500 years?
