All qualified physicists, biologists, cosmologists and geologists agree, on the basis of massive, mutually corroborating evidence, that the earth's age is at least four billion years.

In Britain you don't usually learn about evolution until you are about 15. I should have thought that you should start at about 8. But I could be wrong about that.

Never say, and never take seriously anyone who says, 'I cannot believe that so-and-so could have evolved by gradual selection.' I have dubbed this kind of fallacy 'the Argument from Personal Incredulity.' Time and again, it has proven the prelude to an intellectual banana-skin experience.
