How do Unitarians understand these verses which seem to say that all created things were created by Jesus?

> John 1:1-3: In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. > > Colossians 1:16: For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. > > Hebrews 1:8, 10: But about the Son he says, ... He also says, > “In the beginning, Lord, you laid the foundations of the earth, and the heavens are the work of your hands. Revelation 3:14, "The Amen, the faithful and true Witness, the Beginning of the creation of God." These verses all say that it was Jesus or God the Son who created the universe. Isaiah 44:24 says: > Thus says the Lord, your Redeemer, and the one who formed you from the womb, I. the Lord, am the maker of all things, Stretching out the heavens BY MYSELF, And spreading out the earth ALL ALONE. According to [Unitarian theology](https://en.wikipedia.org/wiki/Unitarianism#Christology) Jesus Christ is a created being and He never preexisted His incarnation as a man. So explain how or why Jesus is identified as the Agent of creation according to the verses quoted?
