A leaf:

How amazing the planet is! I wonder if those who purpose to believe in evolution have ever spent a day outside? For example, if I were to set a simple leaf before you and ask you what you saw, what would you say? A plain old leaf, thin and wispy, hugely common…perhaps? Well, in fact, this leaf in front of you is actually a solar power plant in clever disguise. It can turn sunlight into energy, amazingly. Not to mention turning carbon dioxide into oxygen, another marvelous feat. It is also a vital source of food for most of the world's living creatures. And beyond functionality it is lovely and comes in various shapes, sizes, and colors. It decays naturally leaving no trace and new leaves take the places of expended ones. Together leaves provide shade and also produce a delightful sound when a breeze blows through them. Wow. Now, if I set before you a man-made solar energy machine, what would you say of it? It works, although it doesn't produce much more energy than it consumes. It does not dually turn carbon dioxide into oxygen, and certainly cannot be eaten. It is not particularly lovely and does not disintegrate naturally. It is costly to produce and definitely does not duplicate itself. Now if I told you that this clever machine was made entirely by accident, by the random meeting of all of the necessary elements, would you believe me? I hope not. Yet some presume to believe that a more highly advanced machine, capable of far greater yields, happened purely by accident. The machinery of nature is so beyond man-made machinery in efficiency, cleanliness, and even beauty that it would be foolishness to fail to attribute them to their awesome Creator. The all-organic, life-giving, vast and loving Creator God.
