"I mean, what do you mean by PURPOSE? You could get these laws of the universe either by randomness or by explaining it via the anthropic principle (and probably either a version of chaotic inflation or M-theory). That's not purpose, that's happenstance"

chaotic inflation or M-theory does not explain the behaviour of human beings to me. You may view human being as not part of nature and dont need explanation. But they are part of nature and goverened by laws of Nature. Humans don't behave like atoms, they behave differently. These is more to nature than partical physics. Well ok you may call it happenstance, I call it a specification or purpose.
