I don't think anything in our solar system was here before the sun. Isn't our sun the center of our solar system?The water on earth is said to be older than sun. There were probably microscopic critters living in the water, similar to the tardigrade that Bo Bo was talking about, and when the sun started burning, those creatures evolved to adapt to their new environment of light and land, etc. New species evolved. There is a type of fish creature that had little extremities which is said to have crawled out of the ocean for food and eventually adapted to life on land is thought to be the beginning of all life on land.
Our planet, the moon, even us, we are all made of star stuff. We live because a sun gave its life. Maybe that's what they got wrong back then. Maybe God said sun and our ancestors thought he meant son.
