I am not sure the above is correct. In fact I believe it to be incorrect.
Consider Genesis 1:1-5, the first day.
1. In the beginning God created the heaven and the earth.
2. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
3. And 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. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
Verse 1 clearly states that 1. In the beginning God created. There is no reason to believe that this did not happen on the 1st day. He could have spoke these into existence just as he did light.
Like I stated, some do, some don't.
Doesn't really matter. Great folks have argued on both sides of the issue.
I would agree with your view EXCEPT:
First: It is not in character with God to create what is without form and void. NO other creative work throughout Scriptures can show without form and void to be part of the character of how God creates.
Second: the word "was" in this poetical selection is accurately translated but NOT meaning as it being created originally in that condition.
For example. I purchased a new car. The car was in a wreck.
See the "was" is not the condition of original purchase, but it "was" in a wreck and no longer in the original condition.
Unfortunately, there is no Scriptures to give the original condition for that is closed and frankly unnecessary to the purpose of the narrative the Scriptures give. It is stated as "was" and therefore, the original was wrecked. Some readers do not recall that poetry (even Hebrew poetry) does not have to entertain every action and recall every work. But poetry (even Hebrew poetry) that presents a "story" is a narrative in short concise terms.
Third: Darkness. There is no darkness in God. In the new Heaven and Earth there is no darkness not even a shaddow. It is impossible for God to deny Himself and Scriptures clearly teach that "God is light, in Him is no darkness." Yet, here in Genesis God is in the dark. Dark is the absence of light, not the presence of darkness. When light is not - darkness is. Because darkness was, God called for light - and there was light. What God desires is treated as a command throughout Scriptures. Light and dark is all the same to God, but because the Scriptures emphasize the state of darkness it places emphasis upon the condition that caused the darkness and without form and void.
Fourth: The land was not exposed until the second day. This was the first time known that water covered the earth, but not the last.
Fifth: There is no alternative, but to recognize the earth's revolution around it's own axis is what declares one day. There is no "time" marked out until the statement of day and night, and then the demarcation of what is a day. Because that day has never been changed (other than for Joshua), and has remained on a 24 hour basis, there is no reason to assume that once night and day were established the 24 hour cycle was also not already in effect.
Note: Without form and void does not have a specific revolution upon axis that can establish what is the beginning from the next beginning. It has no form, it has no fixed estate. The Hebrew poetry words are used to show confusion and like a boiling or churning action. The fact that what constitutes a "day" being specified in the Scriptures, conforms to the poetical form of assuming the reader knows that without form and void was corrected into some established form that was not void.
Sixth: Lest some readers think I am not a holder of a literal six day creation, let me make that statement clear. I hold to the view of a six day creation, and that is six 24 hour time periods in which all creation took place.
Seventh: That view (as stated in # six) does not conform the Creator to have only created the current heavens and earth and never having created before nor in the future. The Lord Jesus Christ states - "I go to prepare a place for you..." He is reflecting that of God's character as Creator. If one reads carefully, it is the "Word" of God (for God is Spirit) that actually formed and did the work - that Word is Christ. He is the Creator and sustains all creation.
