No, I wasn't saying that. I was saying that such a catastrophic event could do who knows what to the earth, and to its strata and so forth. Perhaps, though, I speak out of mere ignorance, and I do apologize if that is so.
Soracilla, the flood, according to the Bible was a global event. That means across the entire planet, torrential rains resulted in catastrophic flooding (unless you want to suggest the rains were localized). The rains continued for 40 days and 40 nights until the tallest mountains on the planet were covered.
Now without getting bogged down in the details (of which there are thousands), at the point when the waters covered the tallest mountain, the rains ceased, and the waters began to recede, the entire planet would have been subjected to sediment deposition. Flood waters would have been carrying so much sediment that as soon as the waters calmed enough, they would have dropped their sediment load. This is not something that occasionally happens, only happens at certain scales, etc., but ALWAYS. It's a law of nature. For an entire year while the waters receded, this would have happened.
The coarsest stuff would have dropped out first followed by finer and finer sediments. Logic tells us that this global flood layer is probably not going to be 1 or 10 or even 100 cm thick, it's going to be several meters thick at the very
least. And again, this layer would have occurred over the entire planet. These sediments would be thinnest at higher elevations and thickest in the lowest elevations - ocean basins, valleys, etc. This layer has not been found in 200+ years of geologic study. Not even by early geologists who were creationists.
We have charts depicting eustatic sea level changes for millions of years. This eustatic curve can be correlated with, among other things, magnetic reversals, global black shale deposition, and global oil formation (which is why it's heavily utilized by oil companies). Your suggestion that we don't know what a flood layer/deposit would look like because we've never seen is in fact based on ignorance (no offense), especially since we are able to pick out hundreds of *other* relative sea level changes in the rock record.
Additionally, early geologists never witnessed astrobleme impacts, and although it took some time, they were able to recognize these catastrophic events and subsequently identify them throughout the geologic record. And those events are MUCH, MUCH more localized - contained within just a few square kilometers, often.
We don't need to witness a global flood to have a pretty good idea of what it would do. Physical laws don't change with time.
