lets take for example the first ten words of the Bible "In the beginning God created the heavens and the earth"......are you saying that anyone who believes those ten words to be fact is insane?.......
If you think that a book written a few thousand years ago by men who knew nothing about the universe is about the creation of the universe you are at best not too swift.
"And the earth was without form and void and darkness covered the face of the deep. And the Spirit of God was hovering over the waters." Then God said, "Let there be light"; and there was light." Genesis 1:2,3
The story is about a time in human history when God gave the law as a light to teach people to distinguish between clean and unclean, good and evil, right and wrong, true and false, the living and the dead, etc., in a world that had been for billions of years in complete darkness where superstition and ignorance covered the face of the deep - prevented people from knowing the true nature of things..
