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.
Mist or Steam?
The Potter’s Hand
We have to deduce a physical process by which a solid ball of stratified sediment, the Earth at the end of the second day, is formed into a hollow sphere with a hydrological system by the end of the third day.
A Theory of First Cause
First cause isn't the same as the Big Bang. The Big Bang, or more accurately we should say nucleosynthesis, is an effect, not a cause. Popular Science (SciPop) promotes speculation about a possible first cause.
God is a Spirit
God is a spirit doesn't mean that God is mystical and undefined, it means His physical nature is that of a vapor. However, God is more than just a Spirit so it's accurate to say that God has a Spirit.
What is the Soul?
Complicated deduction is an exercise in mental agility, but sometimes things fall in your lap. We have an explicit statement that the human soul is a gravity node. How so? God has put eternity, a singularity, in our hearts.
Deep Calls to Deep
We're going to ignore the possibility that Psalms 42:7 is flowery poetic language intended to teach us something spiritual. Instead we're going to use it as the description of a hydrological system in a test of Hypothesis 22.
The Great Deep
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.
The Third Heaven
The third heaven is the dome or firmament, which is a sea of glass. It's a rigid crystalline sphere on the edge of space which formed in response to the creation of gravity on the second day.
The Father of Lights
The phrase "the father of lights," is sweet and poetic. It's spiritually accurate in identifying two roles of God the Father. It's also accurate physics.
Hypothesis 22
For those of you who think that those of us who believe in a literal interpretation of the Bible are stupid, we can show that even Biblical literalists don't have an inkling of the extent to which the Bible can be taken literally.
