This sounds like the Egg and the Hen question but I am curious about this. If universe came first and created physical laws for itself, then what created the law or the principle as a consequence of which the universe came into existence in the first place? And if there where pre-existing physical laws that governed the big bang or whatever the origin of the universe was, then where did those laws come from and what were they a part of? If we assume that creation and destruction of universe is cyclic and the same laws are carried onto the next creation and destruction cycle then shouldn't the law which is governing this cycle be a consequence or a part of some bigger something (like a mega-verse). Whichever the case, we again come down to same basic question as in the title.

Thanks.
