First you are wrong, the trinitarian model works perfectly with the old testament.

God creates in Genesis 1:1

The word (who John would later write became flesh) creates in Psalms 33:6

Psalms 33:6
[6]By the word of the Lord the heavens were made, And all the host of them by the breath of His mouth.

The Spirit creates in Job 33:4

Job 33:4
[4]The Spirit of God has made me, And the breath of the Almighty gives me life.

And to specifically demand "Holy Spirit" is very weird considering in the New Testament, the Holy Spirit is also called "The Spirit" numerous times.

Again the Holy Spirit is explicitly mentioned in Isaiah,

Isaiah 63:10
[10]But they rebelled and grieved His Holy Spirit; So He turned Himself against them as an enemy, And He fought against them.

Secondly, you are Missing the point again. Let me put it in bullet point for you.

- You say the US in "Let US create man" refers to God addressing the divine council. Note the statement is LET US CREATE. So if the US indeed is the divine council then the divine council CREATED alongside God.

- The Hebrew scriptures over and over again like a beating drum says GOD ALONE created creation and man.

So the divine council does not work.

So either show me a scripture that says the divine council participated in creation OR that the divine council also created man OR that man is also made in the image of the divine council or concede it does not work and give me another model or interpretation that accounts for the two points above.

Surprisingly, the trinitarian model fits very well with the Old Testament, your divine council model does not. If it does please prove me wrong and provide the scriptural references I've been begging you for for the last three comments.
