Possibly a question for another thread, unless Naomi doesn't mind?
Briefly, though, it is the energy of dying and exploding stars that is needed to create the heavier elements -- Carbon, Oxygen, Iron, etc (and basically everything with a higher atomic number than 4 or 5). These elements are what make up much of modern life, and they were produced in novae and supernovae, and blasted out into space. Eventually some of that material arrived here, in the Solar System, and ultimately became the Earth and the other planets and all life in this system. In a sense, then, we are made of stardust.

Do we need a creator at all?
