The sun wasn't even created at first, so how would an earth day even make sense at the start of creation?

when that book was written by goat herders, they had no concept of celestial bodies.

For centuries the world believed the universe revolved around earth.
But the sun is a younger star than many, so wouldn't he have created other worlds first?
And if the book is his words why did he not better explain the science of his design?
