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, and let them be lights in the expanse of the heavens to give light upon the earth.” And it was so. (Genesis 1:14-15) [ESV]

The moon is not a star nor does it emit light; it only reflects the light of the sun (and a small amount of light from the earth, which also originated from the sun).

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. And God set them in the expanse of the heavens to give light on the earth, to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. (Genesis 1:16-18)

Physically, the sun does not change. The amount of light which reaches a specific location on the earth will vary because the earth rotates. A location will move away from direct light from the sun, but the light received (at night) is still from the sun. In other words, even when not directly visible, the sun is still the greater light (in the night sky).

The correct way to explain this system is to say there is one great light which becomes lesser by the combined factors of the earth's rotation and the presence of the moon. Or simply, God made the greater light lesser to rule at night.

וַיַּעַשׂ אֱלֹהִים אֶת־שְׁנֵי הַמְּאֹרֹת הַגְּדֹלִים אֶת־הַמָּאֹור הַגָּדֹל לְמֶמְשֶׁלֶת הַיֹּום וְאֶת־הַמָּאֹור הַקָּטֹן לְמֶמְשֶׁלֶת הַלַּיְלָה וְאֵת הַכֹּוכָבִֽים׃

While "two lights great" is plural, "the light" הַמָּא֤וֹר which rules the day is the identical with "the light" הַמָּא֤וֹר which rules the night.

Can Genesis 1:16 be read to give a more physically correct description of the system God created?

The answer is simply "no", for at least two reasons.

The first reason is that there is no indication that any Biblical passage is intended to teach a technical, scientific or even historical truth. The majority of the Bible presents the religious and political viewpoints of its various authors and redactors relative to competing viewpoints at the time of their writing. These authors lived and wrote in a time before what we now call "science". Furthermore, science doesn't purport to be true or "the Truth", science only purports to providing the best current understanding of natural phenomena. Because of this mismatch in purposes it is an exercise in futility to try to back-read science into the ancient world and into the Bible in particular.

The second reason is that the grammar of the verse does not support such a reading. The main verse in question is Genesis 1:16, the MT of which is:

וַיַּ֣עַשׂ אֱלֹהִ֔ים אֶת־שְׁנֵ֥י הַמְּאֹרֹ֖ת הַגְּדֹלִ֑ים אֶת־הַמָּא֤וֹר הַגָּדֹל֙ לְמֶמְשֶׁ֣לֶת הַיּ֔וֹם וְאֶת־הַמָּא֤וֹר הַקָּטֹן֙ לְמֶמְשֶׁ֣לֶת הַלַּ֔יְלָה וְאֵ֖ת הַכּוֹכָבִֽים

The first grammatical problem is that the word מאור (ma'or) which appears three time in the verse is not the same as the word אור (or), meaning "light" as in Genesis 1:3. The word מאור in Genesis 1:16 has a mem (מ) prefix, meaning something that gives light, a source of illumination rather than light itself. This distinction is critical to correct understanding of the verse but is not apparent in any of the main English translations because in English there is no distinction between "light" meaning light itself and "a light" meaning a lamp or source of illumination. Only Young's Literal Translation comes close to providing this distinction:

And God maketh the two great luminaries, the great luminary for the rule of the day, and the small luminary -- and the stars -- for the rule of the night.

The second grammatical problem is the form of the verse, which is

God made two: this one and that one

This is a common form in the OT, for example, Exodus 29:38-39 (KJV):

Now this is that which thou shalt offer upon the altar; two lambs of the first year day by day continually. The one lamb thou shalt offer in the morning; and the other lamb thou shalt offer at even:

No one would suggest that this form indicates that the two lambs (or two sources of light) could be identical.

Quite clearly, the "lights" refer to light sources rather than more specifically light emitters (over and against reflectors—whereas both can be called emitters). The moon is a source of light for the earth, and thus a light source, even if a secondary one. It's also fitting that the maidservant of the sun should emit less light during "the darkness" which is separated from "the light."

Also, we don't expect people today to say, "I awoke at the time when the earth's rotation is such that it gives the impression that the sun is rising in the sky." We just say "sunrise." The Bible may use the same kind of language—and does.

The first day of creation the being created is the law of righteousness ,Psalms 119,also Proverbs 6:23; the darkness is unlawful life before God Most High! The second time light is created is the stars like our sun also the moon, the fourth day.

From my own aspect on earth, I see two luminaries. I may, or may not, know the physics of the two objects, but what I can see is that one light is greater and one light is lesser. To me, from other places in scripture (such as, 'the sun of righteousness shall arise', Malachi 4:2) I understand that Jesus Christ is the greater light that shines upon the world of men.

In him was life and the life was the light of men, John 1 : 4.

The lesser light that ruled the night is the light of the law, the knowledge of good and evil, which law was a schoolmaster to bring me to Christ, the true light.

No, I do not think that Genesis 1:16 can be read to give a clearer understanding of the physics involved because that is not what the first chapter of Genesis is about - a technical explanation of heavenly bodies.

Genesis chapter one is a profoundly spiritual expression of what creation is, in and of itself. And a profound revelation of the new creation, for those who have eyes to see it.
