God's wisdom is expressed with His words as well as seen in His creation. The word of God is wisdom, or do you deny this to be true?
Jesus was born of Mary, he did not just "become".
What you have not refuted is that in the 1st century both the Jews and the Greeks understood "logos" (dabar in Hebrew) to be the expression of God's predetermined plan for a changing universe. You are also basing a doctrine on 18 verses that is defeated in the balance of John since in this same book Jesus affirms that the Father is the only true God (17:3), that the Father is his God (John 20:17), that the Father is greater (14:28), his works bear witness of the Father's power (5:36), and etc. If Jesus was God then he would should have said so in plain language (which he did not) or he sinned by bearing false witness to the source of his life, his power, his words, and his authority.
