No one has attempted to say WHY the law exist?
But the question I asked was WHY DO LAWS EXIST!!
No it wasn't. It may have been what you meant to ask, but you didn't.
Since you ask, the (fundamental) laws exist because there are only a finite number of varieties of (common, at least) fundamental particles. Higher-order laws again are the result of limited variety in nature.
Saying that "laws of nature exist" is really just a (misleading) reification of this fact.
But I'm keen to learn your explanation. Does it involve magic?
