The water and light in Genesis 1:1-3
The water can be found in Genesis1:2;
"and the darkness was without form or shape, with darkness over the abyss and a mighty wind sweeping over the waters."(NAB)
As you can there was no creation yet as described, Jesus the Logos must be conceived first in the waters of the pure womb of a Woman mystically.
Now you also mentioned Proverbs8:22, that is the Spirit of Created Wisdom and this is the First Act of God as it pertains to His Divine Plan. The spirit of Created Wisdom envelops the Alpha & Omega, meaning when God desires to create mankind to share His Infinite Glory in eternity, God had to first lay down His Divine Plan.
Genesis1:1 and Genesis1:2 is the blueprint of God's Divine Plan in eternity.
Genesis1:1 pertains to the "Way of the Cross" as revealed in the Hebrew word "Bereshit" look at the explanation below.
and Genesis1:2 pertains to the "Mystery of Incarnation", meaning after God had laid out the Divine Plan of Salvation, He then conceived how to incarnate the Logos and that is, it need to born of a Woman. That's why Genesis1:2 was described as the Spirit is hovering the waters or forming the Logos in the waters of the pure womb of a Woman.
Regarding your understanding about Jesus Christ the Begotten Son of God.Jesus Christ soul is a mystery, although it is a human soul the bible tells us it pre-existed in eternity in the bosom of the Father.
New American Standard Bible
No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.(John1:18)
When we say bosom, Jesus substance is the same with the Father. That's why Jesus said;
"I and the Father are one.” (John10:30)
and St.Paul tells to the Collossians what is the humanity of Jesus is as the Son of God;
"The Son is the image of the invisible God, the firstborn over all creation. "
Genesis1:1 is the Blueprint of God's Divine Plan for Salvation that reveals to us that God foreknew that Adam & Eve will fall to temptation and that the sending of Jesus to Redeem mankind is not because Adam & Eve committed the original sin but the Omnipotent God in desiring to share His Glory to created mankind has to conceive a Divine Plan how every human being can enter His Kingdom.
And Genesis1:1 revealed that there's only one way for mankind to enter the Glory of Heaven and that is what Jesus Christ humanity offers it's called the "Way of the Cross".
Jesus in Genesis: 1. The First Word of the Bible
The video would tell us that God conceptualize first His Divine Plan and who are the Key Players to fulfill His Dream of having a created mankind achieve Theosis/Divination for it to be worthy to enter His Kingdom.
The Divine Plan is very simple "God will create a soul and the soul will need a human body to animate and that soul must return to God Divinized or Glorified, How?
The soul of man can only be Divinized/Theosis by embracing the only way, only one way that what's Jesus Christ had shown to all of mankind, that's why God the Father sent Him to show us the Way. What is the Way?
"THE WAY OF THE CROSS" is the only way to enter God's Kingdom.
The Cross is the Wisdom of God as Jesus is the Wisdom of God.We cannot separate Jesus from the Cross.
Genesis1:1-2 is the blueprint of God's Divine Plan for the Salvation of Mankind, and God had created a spirit of Wisdom to envelop this whole plan. And that is the Spirit of Wisdom mentioned in Proverbs8:22.
But this kind of teaching need a lot of graces to understand that's why the Apostles said in scripture;
"Brothers, I could not address you as spiritual, but as worldly—as infants in Christ. 2I gave you milk, not solid food, for you were not yet ready for solid food. In fact, you are still not ready, 3for you are still worldly.(1Corinthian3:1-3)
Hope this explanation shed light on your inquiry about the "waters" in Genesis1:2 as we need the whole picture from the point of view of the Spirit of Created Wisdom to grasp the beautiful plan of God for all who will follow His Divine Will.
After Genesis1:1 and Genesis1:2 had been written only then the creation time begins..."Let there be Light was uttered as Jesus Christ is the LIGHT that was already formed mystically in the Eternal Now of the Abba Father.
