Here is more confirmation, regarding the creation and God's nature
Isaiah 44
There Is No Other God
6 “Thus says the Lord, the King of Israel,
And his Redeemer, the Lord of hosts:
‘I am the First and I am the Last;
Besides Me there is no God.
7 And who can proclaim as I do?
Then let him declare it and set it in order for Me,
Since I appointed the ancient people.
And the things that are coming and shall come,
Let them show these to them.
8 Do not fear, nor be afraid;
Have I not told you from that time, and declared
it?
You
are My witnesses.
Is there a God besides Me?
Indeed there is no other Rock;
I know not one.’ ”
24 Thus says the Lord, your Redeemer,
And He who formed you from the womb:
“I am the Lord, who makes all things,
Who stretches out the heavens [c]all alone,
Who spreads abroad the earth by Myself;
We have First and Last as pertaining to God, and how He is the Rock, and God who makes all things by Himself
All those things are also shown in scriptures as Christ who says He is the First and Last, the Rock that followed Israel in the wilderness and the Rock was Christ, and for by Him all things were made in heaven and earth for Him, through Him, and in Him all things are.
Rev 1
10 I was in the Spirit on the Lord’s Day, and I heard behind me a loud voice, as of a trumpet, 11
saying, [g]“I am the Alpha and the Omega, the First and the Last,” and, “What you see, write in a book and send
it to the seven churches [
h]which are in Asia: to Ephesus, to Smyrna, to Pergamos, to Thyatira, to Sardis, to Philadelphia, and to Laodicea.”
12 Then I turned to see the voice that spoke with me. And having turned I saw seven golden lampstands, 13 and in the midst of the seven lampstands
One like the Son of Man, clothed with a garment down to the feet and girded about the chest with a golden band. 14 His head and hair
were white like wool, as white as snow, and His eyes like a flame of fire; 15 His feet
were like fine brass, as if refined in a furnace, and His voice as the sound of many waters; 16 He had in His right hand seven stars, out of His mouth went a sharp two-edged sword, and His countenance
was like the sun shining in its strength. 17
And when I saw Him, I fell at His feet as dead. But He laid His right hand on me, saying [i]to me, “Do not be afraid; I am the First and the Last.
1 Cor 10
Moreover, brethren, I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea, 2 all were baptized into Moses in the cloud and in the sea, 3 all ate the same spiritual food, 4
and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ. 5 But with most of them God was not well pleased, for their bodies were scattered in the wilderness.
1 Col 1
15 He is the image of the invisible God, the firstborn over all creation. 16 For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or [e]principalities or [f]powers. All things were created through Him and for Him. 17 And He is before all things, and in Him all things consist. 18 And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence.
