“There is a massive, irreconcilable conflict between science and religion. Religion was humanity's original cosmology, biology and anthropology. It provided explanations for the origin of the world, life and humans. Science now gives us increasingly complete explanations for those big three. We know the origins of the universe, the physics of the big bang and how the basic chemical elements formed in supernovas. We know that life on this planet originated about 4 billion years ago, and we are all descendants of that original replicating molecule. Thanks to Darwin we know that natural selection is the only workable explanation for the design and variety of all life on this planet. Paleoanthropologists and geneticists have reconstructed much of the human tree of life. We are risen apes, not fallen angels. We are the most successful and last surviving African hominid. Every single person on this Earth, all 7 billion of us, arose 50,000 years ago from small bands of African hunter-gatherers, a total population of somewhere between 600 and 2,000 individuals.”
