Can we make the case that the phrase "When He strengthened the fountains of the deep," means "sealed shut with lava or magma?" We'll need to look at other passages where the word translated as strengthened occurs.
The context of the mist that went up is important. It's part of the narrative of the week of creation when the fountains of the great deep had to be sealed after the deep had drained through them into the interior of the Earth.
The fountains of the great deep are channels through the crust and mantle of the original Earth through which water drained into the great deep. They were later used to flood the Earth in the time of Noah.
The deep and the great deep are both translated from the same Hebrew word, tehom. The difference signifies a transition from the deep where Earth was created to when the great deep is in the interior of the Earth.
Knowing how the firmament is constructed lets us interpret scripture and account for empirical observations of the cosmos, including 90% of the mass of the universe that mainstream science (SciPop) can't find.
For generations the evolution crowd has used the quirky Australasian fauna to belittle Creationists. How, the rhetoric goes, did the Monotremes and Marsupials manage to swim to Australia after Noah's flood?
We (that's me and the Holy spirit) make a contextual connection between tehom and sheol because they're both used to refer to the underworld realm of the dead, also known as the grave.
The fountains of the great deep burst open because the expansion of hell caused the waters of the great deep to heat up to boiling point where they were in contact with the core.
We need to understand where the Iridium anomaly is found in the stratigraphic column as compared to the sequence of Noah's flood that we can deduce from the sedimentary evidence.
We're relating the events of the Bible to natural processes for which there is physical evidence. There's abundant physical evidence of Noah's flood: the stratigraphic column from the Cambrian to the Quaternary.
