''There is no valid reason for even asking the question any more than asking the question "Why wasn't I born into a different family" or "What if different people see the color green differently". It is all philosophical nonsense. At least from the standpoint of science.

We are here because we are here. End of question.''

Well, whether questions have meaning or not also depends on the circumstances. If there exists only a single universe, then you are right. If a whole ensemble of universes exists then the question why we live in this particular universe with the particular laws of physics does have meaning (you could rule out ensemble theories which predict the wrong laws of physics).
