Linking to the above discussion, CTD, is as funny as you linking to the discussion of polonium halos with RAZD here. There are a couple of people who understand the topic and several whose questions show they do not. Those are the same people who want to claim that radiometric dating is unreliable. One guess which group that is.

And yet no one here has dealt with the evidence I've actually presented. It has been consistently ignored and now seems to have been conveniently forgotten. Here is a reminder:

1.) The huge quantity of biologically-derived material buried in the earth, which includes coal, oil, and limestone. There are trillions of tons. Yet according to YECs, life on earth has only existed for 6,000 years.

2.) How do you get large evaporite layers when even a small layer takes a long time to form? How do you get blueschist, limestone or varves from a 6,000 year old earth and a flood?

3.) Why is there no evidence of genetic bottlenecks in all species dating to 6,000 years ago?

4.) 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?

5.) Radiometric and cosmogenic dating methods show the earth to be billions of years old, not 6,000. When applied correctly, these methods correlate with each other and with other methods consistently.

6.) 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.

7.) 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.

8.) Coprolites – Coprolites, which are fossilized turds, are preserved throughout the fossil record. How does a flood have animals constantly crapping in the midst of a flood after they are exterminated?

9.) Detailed layering – How could a global flood create thousands of layers seen in several geologic formations, each of which requires a different depositional environment?

10.) Studies on the human Y-chromosome also show that a global flood could not have happened as the Old Testament claims. If it were true, than all males would have received their Y-chromosome from Noah. The Y-chromosome only exists in males and is passed from father to son, so all of Noah's sons would have received his Y-chromosome. This means that all differences in the Y-chromosomes in modern human males would be mutational differences accumulated over the past 4,000 years or so. This should amount to very little variation. However, genetic studies show that in order to account for the genetic differences in human Y-chromosomes, you need a timespan of approximately 60,000 years. Similarly, studies on mitochondrial DNA (which travels down the female lineage) show that it has too much variation to support the idea of Eve living 6,000 years ago. There is ample evidence in human mitochondrial DNA for a bottleneck event in the early history of homo sapiens but in order to explain the subsequent genetic variation in human mitochondrial DNA requires 140,000 years of accumulated mutations.

11.) Why are there layers of mature marine environments, including 20-30 year old brachiopods with stalks intact, within mountains?

12.) Where is the actual geological evidence for a flood? The Channeled Scablands in Washington state show evidence of repeated catastrophic flooding, yet the Grand Canyon does not. Here is the post with links to evidence from a previous thread.

All we have had here in response to the above so far is red herrings: claims about some kinds of oil forming quickly (which do not address point 1); a video which erroneously depicts a certain deposition process; polystrate trees being a "problem." Why is that, when any one of the above points is a pretty convincing argument for there having been no global flood? And we haven't even touched on the impossibilities of Noah's Ark yet. Seems to me that if creationists here are going to continue to insist that it happened, they've got some explaining to do.
