Stars, 3 days later.
Then God said, “Let there be lights in the expanse of the heavens to separate the day from the night, and they shall serve as signs and for seasons, and for days and years; 15 and they shall serve as lights in the expanse of the heavens to give light on the earth”; and it was so.
-- Genesis 1:14-15
God made sure that man had no reason to worship the sun, moon, and stars. They were not part of the first day of creation and caused the light. They because just another thing or things that were part of creation. That was the plan and a good one, but people down through history have still worship the creation rather than the Creator. We as Christians are careful not to do that, but there are other gods that call our names. Some have names like pride, fame, riches, and power. They all pull us away from God and we need to resist that pull.
