That's not backwards... creation of the universe and all the light within it would have occurred prior to the birth of our sunWhat real reason was there for creating the sun after he already created light? It needed a source to illuminate the Earth? Wasn't it already illuminating it? Plus, the way it's described in the bible is silly.
Genesis 1:4-5God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
Genesis 1:16-19And God made two great lights; the greater light to rule the day, and the lesser light to rule the night ... to divide the light from the darkness: and God saw that it was good. And the evening and the morning were the fourth day.
Backwards wasn't the right word. More like unnecessary and head scratching.
