Charles Darwin spent more than twenty years of his life gathering evidence for the theory of evolution. He presented it in 1859 with the publication of On The Origin of the Species by Means of Natural Selection, which—drawing on observations of an incredible variety of animal and plant life from all over the world and integrating it with geology, geography, animal husbandry, and the available fossil record—proved the theory of evolution. This says nothing of the observations and experiments of later scientists, which bolstered and expanded the theory.
Faith in “God’s word” is not an intellectually defensible argument against a scientific theory. Isaac Newton, responding to criticisms of his theory of optics, indicated the kind of evidence required to properly dispute a scientific theory:I could wish all objections were suspended . . . from any [grounds] other than these two: of showing the insufficiency of experiments to prove . . . any part of my theory, . . . or of producing other experiments which directly contradict me, if any such may seem to occur.Isaac Newton, the greatest scientist in history and himself a religious man, would never have taken seriously faith-based arguments against a scientific theory—and neither should anyone else.
