The article is actually an excerpt from the book Hawking and Mlodinow co-wrote called 'The Grand Design,' which is set to be published by Bantam Books on September 7, 2010.
The Editorial Review by Dr. Hawking of The Grand Design' on Amazon.com states, 'In The Grand Design we explain why, according to quantum theory, the cosmos does not have just a single existence, or history, but rather that every possible history of the universe exists simultaneously.'
And, 'We question the conventional concept of reality, posing instead a "model-dependent" theory of reality. We discuss how the laws of our particular universe are extraordinarily finely tuned so as to allow for our existence, and show why quantum theory predicts the multiverse--the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature.'
So far, 370 comments appear after The Wall Street Journal article -- and no doubt many more will arrive in the future. (Just in the time it took me to write this article twenty new comments have appeared -- we're now up to 390.)
You have your reasons to believe what you believe as to the question: How did we come to be?
