Even when you believe the Trinity, it was still not Jesus who created the universe. Jesus, the Son, is God on earth. Once you try to reason that Jesus created the universe, then by the same reasoning, you assume the Father, Son, and Holy Spirit to just be interchangeable terms. You wouldn't say the Holy Spirit died on the cross for your sins, would you?
Jesus, the Holy Spirit and God created the universe together. They are one and the same. That is what the bible teaches.
Genesis 1:26 And God said,
Let us make man in
our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
John1:1 In the beginning was the Word, and the Word was with God, and the
Word was God.
2 The same was in the beginning with God.
3
All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
6 There was a man sent from God, whose name was John.
7 The same came for a witness, to bear witness of the Light, that all men through him might believe.
8 He was not that Light, but was sent to bear witness of that Light.
9 That was the true Light, which lighteth every man that cometh into the world.
10
He was in the world, and the world was made by him, and the world knew him not.
14
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
