Darwin said: "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." When you read this book, you will see that Darwin's theory has absolutely broken down, just as he feared it would. Creatures in nature have extremely complex body systems. A thorough examination of the feathers of a bird, the sonar system of a bat or the wing structure of a fly reveals amazingly complex designs. These designs clearly indicate that all living things are flawlessly created by Allah. The theory of evolution advanced by Charles Darwin in the 19th century denies creation and suggests that design in nature came into existence “spontaneously and accidentally” through natural processes. According to the theory of evolution, the basic mechanism of this phenomenon is “gradual development.” Scientific developments in the 20th century, however, have shown that designs in creatures cannot be attributed to “gradual development.” Living bodies consist of organs made up of intricate components, the absence of even one of which would render that organ useless. Even these “irreducibly complex” organs alone clearly prove that life cannot be accounted for by natural causes but was flawlessly created by Allah. In this book, you will see the proofs of Allah’s perfect creation.
