Even among Christians there are differing opinions as to how long it took to create the heavens and the earth; millions of years, thousands of years, six days? So what does the Book we all hold dear say on the subject.
Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And God saw that it was good. And there was evening, and there was morning the third day.
Then God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve to mark the seasons and days and years, and let them be light in the expanse of the sky to give light on the earth.” And it was so. God made two great lights – the greater light to govern the day and the lesser light to govern the night…… And God saw that it was good. And there was evening, and there was morning the forth day.
I leave you with this thought: Plants can only live without sunlight for around 30 days.
