An objective, world wide record of sedimentary activity agrees with the biblical text which states the earth was primarily covered with water at first; more than enough to result in a world wide deluge when the "fountains of the deep durst forth."

No, it isn't. You are not addressing the evidence that geology does.

[Fester Chugabrew]

Geology tends to have two schools of thought: Uniformitarianism and catastrophism. Both processes are evident. Neither affords the certitude we would like to have when attempting to understand its entire history. The stark delineations in the diagram you posted I tend to attribute to catastrophic processes. Almost all of the fossil record I would also attribute to catastrophic processes. Can you prove me wrong? No. But you can offer up some reasonable scenarios to counter my own understanding.
