Christians, what is your take on the double creation of light in Genesis?

In the 1st book of the bible God creates light twice, on the 1st day and the 4th day.

Genesis 1:3-5
3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he 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.

Genesis 1:14-19
14 And God said, “Let there be lights in the vault of the sky to separate the day from the night, and let them serve as signs to mark sacred times, and days and years, 15 and let them be lights in the vault of the sky to give light on the earth.” And it was so. 16 God made two great lights—the greater light to govern the day and the lesser light to govern the night. He also made the stars. 17 God set them in the vault of the sky to give light on the earth, 18 to govern the day and the night, and to separate light from darkness. And God saw that it was good. 19 And there was evening, and there was morning—the fourth day.

It's established that God created day and night on the 1st day but goes on again to create day and night on the 4th. There have been many attempts to explain this but no explanation yet has been truly satisfactory. What are your thoughts
