How do laws evolve then? (Kind of funny if the answer is they spontaneously come into being).

The topic concerns origins of life. Your point is mine. Evolution as a theory is simple, and examples abound. This does not mean that it is correct to use it as widely as is commonly done.

How do laws evolve then?

Repeated observations of an event sufficient to describe a general pattern. They could, in fact, be found to be wrong later, such as Newton's Law of Universal Gravitation.

Laws attempt to explain what the universe does. Theories attempt to explain why the universe does it. They are two different kinds of statements.

A law is a simple description of something in nature. A theory is an explaination for it. You can write a law in a single equation, wheras a theory requires a whole library.
