Evolutionists, when confronted with the principles of thermodynamics, and especially the second law, often resort to two defences: that increase of order goes on spontaneously in crystallisation; and that the receipt of energy from the Sun somehow changes the matter. It is shown here that neither of these contentions is valid. So it is impossible, in the light of established physical principles, that the order in the world around us could have arisen spontaneously from chaos.
