From Genesis 1
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.
6 And God said, "Let there be an expanse between the waters to separate water from water." 7 So God made the expanse and separated the water under the expanse from the water above it. And it was so. 8 God called the expanse "sky." And there was evening, and there was morning-the second day.
9 And God said, "Let the water under the sky be gathered to one place, and let dry ground appear." And it was so. 10 God called the dry ground "land," and the gathered waters he called "seas." And God saw that it was good.
11 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 it was so. 12 The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. 13 And there was evening, and there was morning-the third day.
As you can see, Vegetation was created in Verse 11, Light was created in verse 3, so while I may have been confused about what you were asking, you were wrong in saying that vegetation was created before sunlight...
Yes, but it looks like the light was divided in verse 16, i.e., day 4. I take the the light to rule the day as the sun and that for the night the moon. No?
Verse 16: And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
