Wrong. Read John 8:24
Jesus said the same thing God said" I AM." Read John 1:1
I say I am all the time, doesn't mean I am god. in john 8 Jesus said I am around 4 times, but all of them are translated as 'I am he' except for john 8.58. In john 8.58 Jesus was saying I am he, the christ.
I do not believe that God's words changed into a 2 cell fetus. I believe the word of god became flesh in a figurative sense, because Jesus is the fulfillment of the word of God.
Jeremiah 31:22 - How long wilt thou go about, O thou backsliding daughter? for the LORD hath created a new thing in the earth, A woman shall compass a man.
the new thing God created was new human male seed. the woman in this verse is Mary, and compass a man means Mary went around a man to conceive.
Thus Jesus is the firstborn of this new creation. It's what "the firstborn of all creation" means.
