Verse 1. "In the beginning God created the heavens and the earth." This is the physical heavens that incorporate all the galaxies in existence. Our solar system was a speck in all that creation.
The earth itself had a form like all the other planets and moons but nothing on the earth did, anymore than the ocean has a form.
It is flat...formless.
What does "void" mean? It means "empty" so the earth was empty...it contained no life at that point. It was initially a giant ball of water.
Light came first. (Genesis 1:3) It displaced the "darkness" and made a division between day and night.
The visibility of the heavenly bodies came later. There was enough light for vegetation to grow.
Who said? If God can suspend a water canopy above the earth by his own command, then he hardly needs an atmosphere to shroud the earth in some kind of blanket preventing light from penetrating to the surface. He doesn't tell us what prevented light from being visible at that time.
As above..."the
surface of the deep" is formless like the ocean.
