The first thing I would point out is that I believe Genesis, so why should I want to show the sun was created before the earth? It wasn't.
The bible doesn't say that the sun is a star, nor does it tell us the distance of sun moon and stars from the earth. As for the planets, the very word "planet" comes from words meaning "wandering star", so I take the planets to be included in that wonderful phrase, "He made the stars also."
As for things about Creation where modern science agrees with what the bible says, two very simple examples would be that the sun does indeed give light to the earth, and scientists would agree that plants contain seeds that grow into the same sort of plants, so acorns always grow into oak trees, not maples, carrot seeds always grow into carrots, not cabbages, and so on. As the bible says:
“Then God said, "Let the earth bring forth grass, the herb [that] yields seed, [and] the fruit tree [that] yields fruit according to its kind, whose seed [is] in itself, on the earth"; and it was so.” (Ge 1:11 NKJV)
It's worth remembering that there are scientists who fully believe in God as Creator and in the Genesis description of that creation.
