Q.Does Hebrew 1:10-12 Prove Trinity?

9.You loved righteousness, and you hated lawlessness. That is why God, your God, anointed you with the oil of exultation more than your companions.10 And: “At the beginning, O Lord, you laid the foundations of the earth, and the heavens are the works of your hands. 11 They will perish, but you will remain; and just like a garment, they will all wear out, 12 and you will wrap them up just as a cloak, as a garment, and they will be changed. But you are the same, and your years will never come to an end.”

With the parellel verse Psalms 102:25-27
25 Long ago you laid the foundations of the earth,
And the heavens are the work of your hands.+ 26 They will perish, but you will remain;
Just like a garment they will all wear out. Just like clothing you will replace them, and they will pass away. 27 But you are the same, and your years will never end.

Since Psalms refers to Jehovah and Hebrews refers to Jesus this would mean they're the same right?Well let's look at the evidence. Let's Go back to verse 9

"You loved righteousness, and you hated lawlessness. That is why God, your God, anointed you with the oil of exultation more than your companions.”
First we see that the author of Hebrew said "That's why God, Your God, anointed you."....

So now we have a conflict. Not only is Jesus and Jehovah both God, but now Jesus the God was anointed by his own Father who is also his God! 

Now let's look at Hebrew 1:13
But about which of the angels has he ever said: “Sit at my right hand until I place your enemies as a stool for your feet”?
With the Parallel Psalms 110:1
Jehovah declared to my Lord: “Sit at my right hand Until I place your enemies as a stool for your feet.”

In verses 5 and 13 the author is pointing out the superiority of Jesus in relation to the rest of the angels. I don't see why he would be compared within the angels if he was already Almighty God.

Jesus surely was there when Jehovah created all things.

1 Corinthians 8:6

" there is actually to us one God, the Father, from whom all things are and we for him; and there is one Lord,Jesus Christ, through whom all things are and we through him"

He also has been ressurrected to 
immortal life, so he will never wear away

Colossians 1:18"..... the beginning, the firstborn from the dead, so that he might become the one who is first in all things; "

Revelation 1:5"and from Jesus Christ, “the Faithful Witness,” “the firstborn from the dead,

If anything, Hebrews 1:10-12 is an argument for modalism as suppose to trinitarianism since the usage of the text here by trinitarians indicate they are the same persons. But since unitarians and trinitarians but admit that they are seperate persons, there is no real problem here.
