“It rests on a misconception of the New Testament mode of speech and conception if we immediately infer that the declaration of Jesus [in John 17:5], that he had glory with the Father before the world was created is simply and necessarily identical in meaning with the thought that he himself preexisted. … According to the mode of speech and conception prevalent in the New Testament, a heavenly good, and so also a heavenly glory, can be conceived and spoken of as existing with God and belonging to a person, not because the person already exists and is invested with glory, but because the glory of God is in some way deposited and preserved for this person in heaven. We remember how, according to the report of Matthew, Jesus also speaks of the treasure (Matt. 5:34); and how also (Col. 1:5 and 1 Pet, 1:4) the hope of salvation of the Christian is represented as a blessing laid up in heaven for them. … Jesus asks for himself not something arbitrary, but what was given to him according to God’s decree and what had always ideally belonged to him. …; the presupposition for this declaration, however, is certainly the thought, which finds decided expression at the close of the prayer in verse 24, that Jesus himself, as the Messiah, did not indeed really exist from the beginning with God, but was the object of the love of God, of His loving thoughts, plans and purposes.”

This is a description of how a Jewish monotheist reads and understands scripture. John, like Jesus, is a Jewish monotheist.
I’ve mentioned to others that trinitarianism (binitarianism and some forms of unitarianism) stand on the literal preexistence of the Son of God. In Jewish monotheism (which is unitarian) it doesn’t; it stands on ideal preexistence - that persons, in this case the Messiah, preexisted in the mind and foreknowledge of God before the person was brought into existense.
In Luke 1:35, the angel tells Mary that the reason the child would be called the Son is God is causal. “For this reason” - the begetting of Jesus by the overshadowing of the Father’s Spirit (the Father’s operational presence and power, personal, but not another person) and the conception of Jesus in the womb of the virgin - is the reason Jesus is called the Son of God.
That isn’t the reason Jesus is called the Son of God in trinitarian theology (nor in binitarian theology, nor some forms of unitarian theology.)
The genesis of Jesus, the Messiah, the Son of God, is in time and place and not, as a child might say, in outer space.
