Hi everyone,
Message 63 presents what I consider would be the best evidence for a global flood, mass extinctions, and also why the number and timing of such events is not consistent with a biblical flood.
Likewise
Trilobites, Mountains and Marine Deposits - Evidence of a flood? presents why I consider fossil evidence of marine life to be evidence of normal marine growth on ocean bottoms, as occurs today, and not evidence for a biblical flood.
Floods do not build mountains and floods do not sort debris. Erosion from impounded water breaking through levees do not create the patterns seen in the Grand Canyon and other canyons, and especially do not produce the erosion patterns that winds produce. The erosion from these kinds of events is more consistent with the scablands: wide flat scoured troughs. Thus a biblical flood cannot explain the evidence of the Grand Canyon, the evidence of many long years of gradual erosion by wind and rain and the undercutting of the river at the bottom.
I agree with ICANT (
Message 317) that it is unlikely that a flood of such short duration as the biblical flood would need to leave any significant evidence of the flood -- it is too short a time for marine growth to occur in the manner shown by the fossil evidence. This is why evidence for mass extinction is more critical, and
Message 63 shows why that argument fails.
Enjoy.
