Essentially, law theorists assert that a chance origin of life is hopelessly improbable. Therefore, they assume, matter simply forms itself into life at some point, obedient to a law of its nature. The theorists do not at present have any idea what factors underlie such a law or how it has worked. Or why it is not working now, so far as we know (in the sense that new types of life are not self-assembling around us). They know that the law exists because life exists, chance is powerless to create it, and devotion to the philosophy of naturalism rules out design. More.

It's the Law of Magical Emergence.
