How would the earth look today if there had been a global catastrophic flood between 5,000 and 6,000 years ago?
Real water isn't magic. It behaves in real ways.
What would we find today--in rocks, in the atmosphere, in flora and fauna?
One correction. According to the Biblical Creationists the earth and universe were formed 6000 years ago. The flood is more like 4000 to 4500 years ago. Oetzi is contemporary with Adam, not Noah.
There would be a jumble of fossils of ALL species that ever lived in one distinct layer. Within that layer the fossils might be sorted by density, but will not be sorted by species. For example, all types of pollen of similar density will be found in the same layer.
In flora and fauna, there will be a monstrous big bottle neck signature in every species of plant and animal pointing to a most recent common ancestor at the time of the flood. This signature would be so common and so ubiquitous that every geneticist would see it as a large and easily identifiable marker like the K/T boundary is to geologists.
World wide, the predominate sign of erosion will be short term water transport. We should not see signs of long term weathering.
Since the earth was created on a few thousand years before the flood, and the flood was basically a one year event, and since the flood mechanisms similar to those we see today have been in play, there should be NO accumulation of weathered rockpiles at the base of cliffs.
Since the earth was created only a few thousand years before the flood, the geological column should consist of three main layers, the lower being all primary rocks, a slim distinct layer containing a jumbled mess of rocks, fossils and debris that is the signature of the flood with a single layer of sedimentary rocks above.
