Answer
Genesis 1:1-2a is not part of the first day.
The first day begins at Genesis 1:2b onwards.
Explanation
Earth was not empty when God created it, so confirms the Scripture
The earth originally was so breathtakingly beautiful that the angels of God shouted for sheer joy!
“When” God “founded the earth” “the morning stars sang together, and
all the sons of God shouted for joy” (Job 38:4,7).
The true God who is perfect never makes anything “empty”!
“For so says Jehovah, Creator of the heavens; He is God, forming the
earth and making it; He makes it stand, NOT CREATING It EMPTY, but
forming it to be lived in. I am Jehovah, and there is none else”
(Isaiah 45:18).
But something happened.
A Satanic Rebellion
The chief Archangel, Lucifer along with other angels was given the jurisdiction in heaven and over the earth (Ezek 28:13-14; Jude 1:6).
But at one time, Lucifer tried to evict God from His throne. He wanted to be the God:
“For you (Lucifer) have said In your heart, I will go up to the
heavens; I will raise my throne above the stars (angels) of God, and I
will sit in the mount of meeting, in the sides of the north. I will
rise over the heights of the clouds; I will be compared to the Most
High” (Isaiah 14:13-14).
This is what Jude is describing:
“And the angels which kept not their first estate, but left their
own habitation” (Jude 1:6).
The earth had a negative effect after the sin of man. Sin always has negative result.
Then what happened after the great sin of Lucifer?
“and the earth ‘hayetah’ without form and empty (bohu)” (Gen 1:2).
The “hayetah” can also be translated as “became” as we can see in other places of Scripture. [See the Annexure]
So, “the earth became without form and empty” because of the sin of Lucifer and his angels.
“How art thou fallen from heaven, O Lucifer, son of the morning! how
art thou cut down to the ground, which didst weaken the nations!”
(Isaiah 14:12).
Thus Lucifer was called Satan or the Devil because he was always opposing God in everything.
Now what?
Renewal of Earth
Psalms 104:30 provides the answer:
“You (Jehovah) send out Your Spirit, and they are created; and
You RENEW the face of the earth”.
This is exactly what we see in the rest of Genesis 1:
“and the Spirit of God moving gently on the face of the waters”
(Gen 1:2b).
God started creating things on earth.
Genesis 1:3 onwards is simply God renewing the face of the earth that was destroyed after the great rebellion of Satanic star wars!
The earth was not CREATED in six 24 hour days.
But the face of the earth was RENEWED in six 24 hour days for human beings.
Considerable time has elapsed between the creation of earth and the Satanic rebellion when earth became useless.
How long did it exist like that?
We do not know.
ANNEXURE
The following reasons made me convinced that the Earth became (hayetah) without form (tohu) and void (bohu):
- Isaiah 45:18:
“For thus said YHWH, Creator of the heavens, He is God, Former of
earth, and its Maker, He established it—He did not create it empty
(tohu), For He formed it to be inhabited: “I am YHWH, and there is
none else”.
God never created the earth as formless and void. As is His usual manner, God creates perfectly. He does not create anything partial or incomplete. God originally created the earth as a habitable place.
- Job 38:4, 7:
“Where were you when I founded the earth?........ when the morning
stars sang together, and all the sons of God shouted for joy?”
When God originally created the earth, it was so breathtakingly beautiful that the angels sang together praising God and shouted for joy. This would not have happened at the establishment of the earth if it had originally been formless and void in darkness.
- The word “was” (hayetah) in the clause “the earth was formless and void” can also be translated as “became” as in the following verses:
“And the man called the name of his wife, Eve; because she became
(hayetah) the mother of all living” (Gen 3:20; LITV).
“And Joseph made it a law until this day on the land of Egypt, the
fifth part is for Pharaoh; only the land of the priests being
excepted; it did not become (lo hayetah) Pharaoh's” (Gen
47:26;LITV, ASV, ESV, GNB, JPS, KJV etc.).
“And there was hail, and fire flashing in the midst of the hail, very
heavy, which never had been in all the land of Egypt since it
became (hayetah) a nation” (Exo 9:24; LITV, ASV, ESV, JPS, KJV etc.).
Thus, it is also possible to translate Gen 1:2 as:
“and the earth became (hayetah) without form and empty”.
- Psalms 104:30:
“You send out Your Spirit, they (the living things) are created,
And You renew the face of the earth (ground)”.
This is exactly what happened in Genesis first chapter. God’s Spirit was moving (Gen 1:2) and God renewed the face of the ground of the earth and its atmosphere.
So we could say fairly well that the earth “became” formless and void due to the Satanic rebellion.
