There are real laws. For example, gravity. Friction. That kind of stuff.
A legal law is an imaginary law.
There is no natural law that prevents you from smoking a fattie. But since there is an imaginary, legal law, you know if you smoke it, the cops will kick your ass.
For a rule to be a law, it must be enforced.
Police enforce our laws.
Then you have religious laws.
So, once again, the are imaginary laws. There is nothing stopping you from having premarital sex.
But, God will enforce this law.
Of course, God is imaginary.
So now... you have an imaginary force, enforcing imaginary laws, on real people.
So I thought to myself... #$%^ it. Why not go all the way?
I'm going to create an imaginary God, to enforce imaginary laws, on some imaginary people.
