Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. Genesis 1:1-2
Formless and empty.
I held out my hand to try to imagine "nothing". That which was in my empty hand had no form.
Yet there was darkness - nothingness - and there was also the Spirit of God in the midst of that darkness and emptiness.
And God said, Let there be light and there was light. God saw that the light was good and he separated that light from darkness. God called the light day and the darkness he called night." Genesis 1:3-5
And here God provided the way for us to see him - before man existed, before the sun and moon were placed in the sky.
The Spirit of God was now distinguishable from emptiness - as clear as night and day.
