2nd Tim 3:16 one of my faves
All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness
Just coz men penned it, doesn't mean it's their ideas. The Bible themes are in harmony throughout, even though it was written over a 1600 year period.
1 thessalonians 2:13 says
Indeed, that is why we also thank God incessantly, because when YOU received God’s word, which YOU heard from us, YOU accepted it, not as the word of men, but, just as it truthfully is, as the word of God, which is also at work in YOU believers
The Bible is the word of God.
And these "laws of nature" God created everything so he created them and his law is perfect. Yes men can be liars and are imperfect too, that isn't new.
So your question can't be answered because you're assuming that the Bible was just "made up"
