Our improbable universe a physicist considers how we got here.

the long version

"Our Improbable Universe will show you why "ordinary existence" is really extraordinary. From the most practical point of view, we really are "star children": the iron in the blood in our veins originated in a stellar explosion billions of years ago. How likely is it that all the myriad conditions for life would come together so precisely? Without positing or denying the existence of a Creator behind it all, the answer to that question is humbling and fascinating. Along the way, Dr. Michael Mallary summarizes the latest findings in cosmology - including string theory, high energy physics, and relativity."--BOOK JACKET.
