Genesis 1:4 - “God saw that the light was good, and he separated the light from the darkness.”

Introduction
In Genesis 1:3, God the Father told Jesus to let there be light. So, Jesus stopped the onslaught of meteors, which kept decimating the oceans back into the atmosphere. The most recent rains could begin to settle down, and light was starting to get through to the ocean's surface below. The sun still was not visible, but as scripture says, Jesus let there be light. His father saw that it was good, and separated it from from the darkness.
What Does Science Suggest This Separation was?
Scientifically, the light that finally reached the oceans was from the sun. The sun could not be seen from the oceans, but that is where the light was from.
As with today, the sun can only light half the earth at a time. From space, there is definitely a separation between the light and the darkness on the earth.
What Does Scripture Say This Separation was?
All Genesis 1:4 says is that the light was good. Genesis 1:5 adds one more detail: evening and morning.
What would be really helpful is if Genesis 1 had actually described where the light was from, and what its separation looked like. Given how closely the science of verses 1 to 3 match the scriptures themselves, the circumstantial case tells us that the science pretty much describes it. But can we find something in the scriptures that is a bit more direct? Yes. In fact, it is described three times!
Psalm 104:6
Psalm 104:2-35 describes the first five days of creation, in order. It is surprisingly accurate. After describing Jesus, riding the Holy Spirit (in cloud form) like a chariot through the clouds, it goes on to say the following...
5 He set the earth on its foundations;
it can never be moved.
6 You covered it with the deep as with a garment;
the waters stood above the mountains.
As we have already seen, the earth was covered with water. Any mountains were under water.
Job 38:9
Job 38:4-13 describes the first four days of creation, in order. It provides surprising accuracy. Looking at verses 8-11, focus on the first half of verse 10, where it describes the earth just before God let there be light...
8 Or who enclosed the sea with doors,
When, bursting forth, it went out from the womb;
9 When I made a cloud its garment,
And thick darkenss its swaddling band,
10 And I placed boundaries on it,
And I set a bolt and doors,
11 And I said, ‘Thus far you shall come, but no farther;
And here shall your proud waves stop’?
In verse 8, imagine the seas being struck by a meteor, trying to escape the earth's gravity like water bursting forth from the womb. They cannot escape. It is as if God had enclosed the sea with doors. Of course, we know those doors are gravity. The waters then rained down back down, as the seas were clothed in clouds and thick darkness. Then, God said, "Let there be light!"
Proverbs 8:27
Proverbs 8:27-30a also describes the first four days of creation, in order. It also provides surprising accuracy, scientifically speaking. With Psalm 104 and Job 38 confirming that the earth was underneath the sun and stars on Day 1, but covered covered in water and cloudy darkness, Proverbs 8:27 brings it all together, by describing...
When He prepared the heavens, I was there,
When He drew a circle on the face of the deep...
Once again, Jesus (speaking as Wisdom) confirms Genesis 1:1, that God prepared the sun, moon, and stars. Then, He let there be light. If you imagine the separation of day from night upon the earth, it is circle! Today, it is a circle drawn through oceans and land. But there was no land back on Creation Day 1. As Proverbs 8:27 says, that circle was drawn on the face of the deep.
