You fail to realise one thing, a copy of anything implies the very thing that is copied is excatly the same expect the age of that copy. If the Father was in existence alone, and then created a copy of himself (Hebrews 1:3), namely Jesus, then how does it make sense that Gods age also copies over to the copy of himself. Again, Jesus being a copy imples he is the same in every respect apart from God eternalness. Moreover, almighty God is NOT a copy of anyone, but Jesus is, therefore Jesus can't be God.
As Jesus himself stated, he lives because of the Father. God almighty lives because of no person or thing. Jesus lacks the main attribute of almighty God, that being having no beginning nor end.
(John 6:57) "..I [Jesus] live because of the Father.."
God is not within time - He is 'ageless' - and Christ is the exact representation.
Jesus said to them, “Truly, truly, I say to you, before Abraham was, I AM”
(John 8:58)
In the beginning God
(Genesis 1:1)
God is 'before the beginning' -- in the beginning, He already 'is' -- before time, unfettered by time, without time, eternal, having no beginning.
In the beginning was the Word
(John 1:1)
the Word 'was' in the beginning -- in the beginning, He already 'was' -- existing before the beginning, before time, unbound by time, without time, eternal.
having no beginning:
All things were made through Him, and without Him was not any thing made that was made.
(John 1:3)
For by Him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities — all things were created through Him and for Him.
(Colossians 1:16)
nothing that was made was made except through Him and with Him and by Him. all things that are made, whether physical or nonphysical, in heaven or on earth, visible or invisible, tangible or intangible, all things are made by Him, through Him and for Him.
if He was made, He was made through Himself and with Himself and for Himself -- and by Himself.
if He was made, He made Himself using Himself for Himself with Himself by Himself.
He was not made:
Jesus Christ is the same yesterday and today and forever.
(Hebrews 13:8)
not changing, not aging, not different before a 'beginning' but self-existing before the beginning, before existence.
the same is said of God and of no other:
O my God, do not take me away in the midst of my days,
Your years are throughout all generations.
Of old You founded the earth,
And the heavens are the work of Your hands.
Even they will perish, but You endure;
And all of them will wear out like a garment;
Like clothing You will change them and they will be changed.
But You are the same,
And Your years will not come to an end.
(Psalm 102:25-27)
I AM THAT I AM
Jesus said to them, “Truly, truly, I say to you, before Abraham was, I AM”
So they picked up stones to throw at him, but Jesus hid himself and went out of the temple.
(John 8:58-59)
they immediately understood that He was calling Himself the Almighty, the Eternal Father, and picked up stones to throw at Him, because not believing, they were not at all uncertain that this was blasphemy.
