Religious people try to convince you that there must be a “god”. One of their major arguments has to do with the direction the world has been going to: “Imagine there is no god, no one to direct things. How come the universe has managed to form such complex structures, given the absence of something to direct things?”
Great! You just proved the existence of the laws of nature!
The laws of nature (or “laws of physics”) are immutable and exact. They govern everything, everywhere and always. They describe how things work and direct things.
“Ok then, but who created the laws of nature? If there are laws, they must have been created by someone!”
The real answer is that this necessity (“they must”) exists only within our limited mental world of thinking. In practice, there is nothing dictating that every law must have a “legislator”. Furthermore, if someone (or something) did create the laws of nature, he/she/it didn’t leave us any evidence for their actions. At least nothing we’ve encountered so far.

But the real twist is to use religion’s own blah-blah to support this. Whenever you ask a religious person “But then someone also must have created God?” – you get these kind of answers. Just take them and switch ‘God’ with ‘the laws of nature’:
The laws of nature are primordial. They are the source of themselves. The laws of nature are not subject to any other laws, or else they wouldn’t be the laws of nature. Only material things that have body, shape and size need another source to create them. The laws of nature, that created this huge and complex universe, are not “material”. They are “laws”, and reside “outside nature”. Of course we cannot understand them thoroughly, as we are limited and have been created by these laws. The laws of nature don’t have “limits”. They are eternal, not limited to any specific place or time. They don’t have a beginning or an end. They do not need or reply upon anything else to create them at some time or limit them, blah blah blah.
