Blockquote We now know the age of our universe (13-14 billion years), the age of the Earth (4-5 billion years), what we and all other objects are made of (atoms), where we come from (evolved from other species), why all species are so well adapted to their environments (natural selection of their DNA). We know why we have night and day (Earth spins like a top), why we have winter and summer (Earth is tilted), what is the maximum speed at which anything can travel (two thirds of a billion mph). We know what the sun is (one star among billions in the Milky Way galaxy), we know what the Milky Way is (one galaxy among billions in our universe). We understand what causes smallpox (a virus, which we have eradicated), polio (a virus, which we have nearly eradicated), malaria (a protozoan, still here but we’re working on it), syphilis, tuberculosis, gangrene, cholera (bacteria and we know how to kill them). We have built planes that can cross the Atlantic in hours, rockets that safely land men on the moon and robot vehicles on Mars, and might one day save our planet by diverting a meteor of the kind that - we now understand - killed the dinosaurs. Thanks to evidence-based reason we are blessedly liberated from ancient fears of ghosts and devils, evil spirits and djinns, magic spells and witches’ curses.

An excellent summation Richard. It's what I invariably take an age to say whenever having to explain to affronted people why I don't believe in their god.
