Quick comment on the "flooded early Earth":
Its not true. It never been completely under the oceans. Earth's continental crust volume has increased (not steadily) since the Hadean. Continental masses were smaller in the distant deep past. If you want a picture of the early Archean times, think of a planet where most land exposed above the sea level would be island chains such as Japan (continental crust above sea level) and Iceland (oceanic crust aboce sea level). As time passes, this evolved to a situation where continental crust would have formed blocks about the size and shape of the Phillipines island chains and/or New Zealand. Eventually larger masses, about the size of Australia were formed and quite later, the volume of continental crust reached a number lose to noways'.
The oldest (good) example we have of crust exposed above sea level dates from 3.7Gy and is located at Isua, Greenland (check de Wit & Furnes, 2013 at Gondwana Research, and sorry, its inside Elsevier's paywall). If you are looking at clastic sediments, its quite possible, regardless of its age, that that they were generated by the exposure of crust to atmosphere -or at least they were above base wave level. Weathering - erosion - transport - deposition. There's no way to create clastic sedimentary rocks without them, most likely related to exposure to the atmosphere (or at the very least above base wave level).
This put, another nail in the coffin of the Bible's cosmology comes from the source of water- volcanic activity and impacts of comets and meteors. This means the oceans growed slowly, and the very early Earth had little if any surface water.
Here's one more nail: The first (indirect) evidence for free water at Earth's surface comes from the Hadean, before the late heavy meteor bombardment. Whatever oceans there were back then were in great part turned in to steam, leaving some some patches of water in the parts of the surface not heated too much by the impacts. As the bombardment faded away, gradually the crust cooled and gradually the oceans grew.
The above can not be correlated with the Bible cosmology. Reality and the Bible's cosmology are not compatible.
