...evolution is not a religious tenet, to which one swears allegiance or belief as a matter of faith.. It is a factual reality of the empirical world. Just as one would not say 'I believe in gravity," one should not proclaim 'I believe in evolution.

Through no divine design or cosmic plan, we have inherited the mantle of life's caretaker on the earth, the only home we have ever known.

How can we find spiritual meaning in a scientific worldview? Spirituality is a way of being in the world, a sense of one’s place in the cosmos, a relationship to that which extends beyond oneself. . . . Does scientific explanation of the world diminish its spiritual beauty? I think not. Science and spirituality are complementary, not conflicting; additive, not detractive. Anything that generates a sense of awe may be a source of spirituality. Science does this in spades. (158-159)

Flawed as they may be, science and the secular Enlightenment values expressed in Western democracies are our best hope for survival.

If spirituality is the sense of awe and humility in the face of the creation, what could be more awesome and humbling than the deep space discovered by Hubble and the cosmologists, and the deep time discovered by Darwin and the evolutionists.

We know evolution happened because innumerable bits of data from myriad fields of science conjoin to paint a rich portrait of life's pilgrimage.

We know evolution happened not because of transitional fossils such as A. natans but because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more.
