God separated light from darkness back at the beginning that is on the first day.
God said, Let there be
lights in the
firmament of the
heaven to
divide the
day from the
night;. I use the Strong's Bible so I can study the original Hebrew. In this case there is no "Let there be" that does not exist in the original. We have three word: "LIGHTS","FIRMAMENT" & "HEAVEN". Firmament here defines the meaning of the word "HEAVEN". (If you want to understand the meaning of these words then context is the key. We look at all the different verses in the book of Genesis, that uses these words.) According to physics the light waves we receive get filtered out in the Firmament or atmosphere. They are even more filtered out in the Ocean. Light only travels through 3,280 feet of the water. After that it is dark and a whole new world of life begins that is bio luminous and they provide their own light. Some of it in the range that we can see and a lot of the world and a lot of the light is outside of our range of sight. Not that many people understand the first chapter of Genesis. God just has not given it to them to understand. A lot of this stuff will be known during the 1000 year reign of Christ. Jesus is the light and light is important. When you control the light you control reality. When you go into a movie theater they control the light and they take you into another world. Then at the end they return you back to the world that you came from. Usually a changed or a different person. This what I studied in College.
The Hebrew people measure their month by the moon. We measure day and night based on the Sun in the Sky. In 240 B.C., the Greek astronomer
Eratosthenes made the first good measurement of the
size of Earth. This is an example of what God has given us to know and to understand. He measured the height of a tower and the depth of a well at noon and used fairly simple math to determine the earth was round and the size of the earth. There is a lot of stuff here, we could go on forever talking about it. The Hebrew Holidays and how they determine the dates and what their significance is. For example: The eight-day festival of Passover is celebrated in the early spring, from the 15th through the 22nd of the Hebrew month of Nissan. So no matter where you are in the world you can determine when Passover is by looking at the moon. The Jewish calendar is based on lunar cycles. Towards the beginning of the moon’s cycle, it appears as a thin crescent. That is the signal for a new Jewish month. Knowing exactly when the month begins has always been important in Jewish practice, because the Torah schedules the Jewish festivals according to the days of the month.

I do not plan to live long enough to see the tribulation. I will be close to 80 by then.
You overcomplicate things, Joshua. On the first three days, God had made/used light (perhaps a supernatural source) for the daytime. On the fourth day, He made the sun, moon, and stars/planets. These are used to separate night and day, and for tracking seasons and years. All of these relate to the passage of time - day, season, year. Today the heavenly bodies separate the night and day and help us track seasons and years.
Thirteen years ago, I translated Genesis 1 entirely in a Hebrew class. There's nothing mysterious about it--nothing missing in English. The words and phrases are clear in their meaning. The first verse says what God did, and the rest of the chapter describes specifically how he did it in six days. God went over and above to make sure we understand these are literal days. Light/darkness, day/night, evening/morning, first day, second day...
Genesis 1:3-5
3 Then God said, “Let there be light”; and there was light. 4 And God saw the
light, that it was good; and God divided the light from the
darkness. 5 God called the light
Day, and the darkness He called
Night. So the
evening and the
morning were the
first day.
Someone once told me that the Hebrew word for create, bara, means creation out of nothing. He explained that millions of years passed between verse one and two, and then God made the rest of creation using existing elements. I went home and opened my Hebrew Bible, determined not to let him get away with speaking of things he did not understand. His--and your--position is clearly bunk because of Exodus 20:11:
11 For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it.
Exodus 20:11 ties Genesis 1:1 and the rest of chapter 1 (and the beginning of chapter 2) into one neat bundle. When my grandfather tried to argue that gap theory was an acceptable position for a Christian to take because Scofield put it in his footnotes, I called him out the same way, and I was only 14. (He refused to assent, but that's because he refuses to "lose" any argument.) Scofield is responsible for spreading a lot of error - especially gap theory and pre-tribulation rapture.
Anyway, there is another word besides bara, ashah, in Exodus 20:11. This is translated "made." Bara and ashah are used interchangeably to describe God's creating action. But when God created man, the word used is bara. Therefore, there's no way the Hebrew goes along with the man's explanation--that God created out of nothing, and then after millions of years, created everything else--including man out of existing elements. It's splitting hairs to try to separate words God uses interchangeably. This man didn't know Hebrew, so he didn't realize that his argument wasn't supported by Hebrew. He probably found an article written by someone who was also mostly uneducated in Hebrew to try to justify his belief in millions of years, and he just embraced it and repeated it. But the Hebrew or English does not allow for this treatment of the clearly written text. There's also no suggestion from the text to read millions of years into it. People are just subjecting God's authority and elevating the authority of man.
You might this is not a big deal. But it was God's Word that created the universe and everything in it. All Scripture is God-breathed and useful for teaching, rebuking, correcting and training in righteousness (2 Timothy 3:16). Jesus is the Word, who was actively involved in all the creating process (John 1:1-3,14). "For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart" (Hebrews 4:12).
Now check this out.
Revelation 19:13-15, 21
13 He was clothed with a robe dipped in blood, and His name is called
The Word of God. 14 And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses. 15 Now out of His mouth goes a
sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God...
21 And
the rest were killed with the sword which proceeded
from the mouth of Him who sat on the horse. And all the birds were filled with their flesh.
Jesus rebuked the Sadduccees on the basis of the tense of a word in the Scripture, since they did not know the Word or the power of God (Mark 12:18-27). They knew the words, of course, but processing words intellectually and believing and embracing them are two very different things. Jesus, the Word of God, Who created by His Word, who provided us His written Word, is the same who will destroy evil men at His coming by His Word. Do you not think that if you treat His word carelessly by refusing to believe the clear parts that He will consider you guiltless? I'm not saying you have to believe in six literal day young earth creation to be saved, but you're on a very slippery slope.
Please take some time to study 2 Peter 3:3-9. It discusses scoffers of the last days who come to reject a literal, bodily return of Christ. It explains that, foundationally, they also refused to believe in God's creation out of water or the worldwide flood. The flood was the first judgment, but if people don't believe the first, it makes sense not to fear God and the future judgment by fire. The verse many people use--I think you already cited it to me--"a day is like a thousand years" to support their rejection of Genesis as literal history is in that same passage, but that use is clearly taking Scripture out of context. It refers to God's patience because He wants to give everyone a sufficient chance to repent and believe in Jesus for their salvation. Please take seriously the Bible's strong words against and the end of such type of rebellion.
I don't know how old you are or when you expect the Tribulation, but what if you are still alive when it comes? You said you'd be 80 so you'd be dead, but that isn't exactly in your hands. People can live to 100, or older. Also, you might not be right on the Tribulation timing - perhaps it's coming earlier than you expect? Will you be ready to endure suffering to obey the Word of God, or will your interpretation of it encourage you to reject your faith or become deceived? It's not good to assume you won't be here, because then you will not be prepared spiritually and emotionally (should you find yourself in it). Jesus gave strong, repeated warnings for a reason. I suppose some people will even say to themselves, "This isn't the Tribulation, because I'm still here, therefore this isn't the mark of the beast..." and therefore justify an action that brings them damnation.
