Because Genesis doesn't talk about election. "In the beginning God created the heavens and the earth". Not elected. God made the expanse. Not elected the expanse. God made the sun and the moon. God made the stars. God created the great creatures of the sea etc. God made the wild animals etc. Then God said "let Us make mankind in our image, in our likeness, so that they may rule...". So God created mankind in His own image.
As I've noted. Bara, or created, has many definitions.
What is an expanse? He made empty air? That's not making anything.
Your response assumes that "mankind" must be something like a material manufacturing. Rather than something like, making a company. Making a home. Making a football team. Etc. sometimes making things does not require a materialistic creation.
I'm going to make an adjustment here:
Genesis 1:16 ESV
[16] And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars.
Now let's try this:
Genesis 1:16
[16] And God *appointed* the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars.
You see. The passage never says anything about fire behind gathered or nuclear fusion or anything. The passage focuses on this:
Genesis 1:14 ESV
[14] And God said, “Let there be lights in the expanse of the heavens to separate the day from the night. And let them be for signs and for seasons, and for days and years,
Signs, seasonal, days and years.
So God is not forming the sun and forming the moon out of atoms and elements. Rather God is appointing the sun moon and stars, designating them for mans purposes of time keeping.
Here's another narrative to help explain:
Well tended is mankind - God's cattle,
He made the sky and Earth for their sake,
He subdues the water monster,
He made breath for their noses to live,
They are his images, who came from his body,
He shines in the sky for their sake;
He made for them plants and cattle,
Foul and fish to feed them...
He makes daylight for their sake,
He sells by to see them.
He has built his shrine around them,
When they reap he hears.
That's instruction of merikare.
The creation in this above narrative is about designating creation for mankind. Appointing it or assigning a purpose. The daylight for their sake, the animals to feed them, the breath for their noses to live etc.
And notice, day 1:
Genesis 1:3-5 ESV
[3] And God said, “Let there be light,” and there was light. [4] And God saw that the light was good. And God separated the light from the darkness. [5] God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.
What does God even make on day 1? He doesn't make anything. So what exactly is He creating here? Day and night. For mankind's purposes. But day and night aren't even material things. What is night? You can't physically create it. He just "called the light day" and "called the darkness night".
God didn't manufacture day and night. He appointed it. Assigned it. Designated it, for people.
Then we go on to chapter 2. "Now no shrub had yet appeared on the earth ... then the Lord God formed a man... the Lord God said ... I will make a helper suitable to him... Then the Lord God made a woman".
Nowhere in Genesis 1 or 2 does it talk about election. Later yes, "but Noah found favor in the eyes of the Lord" - at that point we can start saying that Noah was chosen (elected), Abraham was chosen, etc.
