We shouldn’t speculate where history is silent.
Absolutely. That's my point.
The historical record is this:
Gen. 1:3 וַיֹּ֥אמֶר אֱלֹהִ֖ים יְהִ֣י א֑וֹר וַֽיְהִי־אֽוֹר
God said: "let there be light." ןיאמר is the first timeline event in the narrative. Light heard God speak and obeyed. Creation is the result of the spoken word.
To argue that God's word was in written form before He spoke would be to argue from silence; pure speculation.
Gen. 1:5 וַיִּקְרָ֨א אֱלֹהִ֤ים ׀ לָאוֹר֙ י֔וֹם God called the light day. God speaks again. If he has written anything up to this point, the historical record is silent.
From a text-linguistic perspective, there are four events recorded on Day One. God said, God saw, God divided, God called. No record of anything being written down.
The second day: ויאמר, ויעש, ויבדל,ויקרא God said, God made, God divided, God called. No record of God writing on the second day.
The third day: ויאמר, וירא, ויאמר,וירא God said, God saw, God said, God saw
The fourth day: ויאמר, ויעש, ויתן,וירא, God said, God made, God gave, God saw
The fifth day: ויאמר, ויברא, וירא, ויברך . . . לאמר, ויאמר, God said, God created, God said, God blessed ... saying, God said
The sixth day: ויאמר, ויברא, ויברך, ויאמר, ויאמר, וירא, God said, God created, God blessed, God said (interesting here "and he blessed ... and he said," while above "and he blessed ... saying"; that would make an interesting discussion), God said, God saw.
Here the text speaks plainly; God speaks 14 or 15 times.
Furthermore, he speaks with Adam and Eve after their sin; he speaks with Cain; he speaks with Enoch; he speaks to Noah; he speaks to Abraham; finally he speaks to Moses.
At Sinai, the host heard voices "speaking" the ten commandments. Then later Moses brings them down carved in stone.
Also in Leviticus, to Moses He says, "SPEAK to the children of Israel." Moses speaks, then writes.
