Creating the molecules of life /

Creating the Molecules of Life discusses origins, including the Big Bang, and the origin of the elements. With a complete presentation and explanation, this book provides evidence that the molecules of life are produced in outer space and how the SNAAP model purports to explain that origin. Extremop...
