So when the Bible says God created the heavens and the earth that’s not describing the creative acts? What makes you think that God has to say “let there be” in order for it to represent Him actually creating something? Why wouldn’t the words “God created” be insufficient for indicating that God has begun the creation process? No verse 1 is the beginning of the creation account hence the term “IN THE BEGINNING GOD CREATED THE HEAVENS AND THE EARTH”. That statement marks the beginning of the creation process. It marks the beginning of God’s work that He rested from on the 7th day.
“Then God blessed the seventh day and sanctified it, because in it He rested from ALL HIS WORK WHICH GOD HAD CREATED AND MADE.”
Genesis 2:3 NASB1995
Why do you think the term “which He had created (bara) and made (asah) is used here? This is a reference to both ex nihilo and ex materia. There’s nothing to indicate that Genesis 1:1 didn’t take place on the first day. Everything points to the entire complete creation and formation process from beginning to end being completed in 6 days.
Genesis 2:1-3 says He completed His work by the 7th day. Genesis 1:1 says that creation process began with the creation of the heavens and the earth. There’s no reason to separate verses 1-5, they all took place on the first day.
In Hebrew, there is no definite article before "Beginning". So some translations way "in the beginning" some say, "in the beginning when" and some say "when God began" etc.
Because there is no definite article, your argument is incomplete. And that's why I can simply quote other translations:
Genesis 1:1 NRSVUE
[1] When God began to create the heavens and the earth,
Genesis 1:1-2 NIV
[1] In the beginning God created the heavens and the earth. [2] Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
Notice verse 2 in the NIV begins with "Now" indicating that it's a continuation of verse 1. The formless earth is a part of verse 1 in a sense, describing background conditions.
Genesis 1:1 NRSV
[1] In the beginning when God created the heavens and the earth,
Genesis 1:1-2 CEB
[1] When God began to create the heavens and the earth— [2] the earth was without shape or form, it was dark over the deep sea, and God’s wind swept over the waters—
CSB is a little different here as well, it starts with "When" and then uses a hyphen to connect verse 1 and 2.
Genesis 1:1 ERV
[1] In the beginning, when God created the earth and sky,
Genesis 1:1 GNBDC
[1] In the beginning, when God created the universe,
Even in NASB if you look closely:
Genesis 1:1-2 NASB2020
[1] In the beginning God created the heavens and the earth. [2] And the earth was a formless and desolate emptiness, and darkness was over the surface of the deep, and the Spirit of God was hovering over the surface of the waters.
You'll see that NASB begins verse 2 with "And" suggesting continuation from verse 1, "and the earth was a formless and desolate emptiness".
Which is to say that it was formless in the beginning.
Genesis 1:3 NASB2020
[3] Then God said, “Let there be light”; and there was light.
And then NASB continues with "then", as in, subsequently, God begins creating with the spoken word.
