No, it doesn't predate Day One. It is included in Day One.In the beginning, God created a mass of seawater in the hollow of His hand.
Isaiah 40:12 Who hath measured the waters in the hollow of his hand, and meted out heaven with the span, and comprehended the dust of the earth in a measure, and weighed the mountains in scales, and the hills in a balance?
1. That is why the earth is "without form and void" -- it's a mass of water. (Unless you want to claim the earth was plano-convex at the time.)
2. He made it seawater, because seawater contains all the natural elements in the Periodic Table. Thus, when the time came, He simply ordered the atoms in the water to link up in the proper order, and behold: the landmass (called "Eden" or "Pangaea," if you prefer) was called forth.
This seawater, I like to call "terra aqua".
3. Notice He is "comprehending the dust of the earth in a measure, and weighing the mountains and hills"? This purports to the Holy Spirit going to and fro on this "terra aqua" and getting the proper measurements for the landmass ("terra firma") that will soon be created.
Genesis 1:1 In the beginning God created the heaven and the earth.
2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
Notice the Spirit is "moving" upon the face of the waters; not "hovering" as Satan's translations say. Anyone who pilots a helicopter would know the difference between "moving" and "hovering."
And as I said, the Spirit is moving to and fro, getting information to use when the right time comes for terra firma to be created.
