Here's how I see it based on my Bible study....
Genesis 1:1 is a preface - The Story of the Beginning of Creation.
Genesis 1:2 documents us the CONDITION OF THE DEEP (empty, null & void) BEFORE anything was Made.
Genesis 1:3 narrates us the bringing forth of the Light BEFORE any work of old.
Genesis 1:4 God divided the Light from the darkness before the start of any creation of our physical world.
Genesis 1:5 Light Day and Night - the 1st. Day.
IOW, I believe the Scripture is documenting us that the first formation of heaven ONLY took place on the 2nd Day (Genesis 1:6-8) - NOT Genesis 1:1.
And other heavens (universes) were made on the 3rd day - again, NOT Genesis 1:1
Do you agree? Your thought please...
