| The divine comedy|
Alan Hayward (1923–2008) was a British engineer, physicist and old earth creationist writer. He is known for his research on fluid density and flowmeters; he wrote a textbook on the subject. Hayward was a Christadelphian and a non-Trinitarian. He accepted an old earth and was critical of young earth creationism. However, his arguments against evolution have been dismissed by the scientific community.
Hayward endorsed a form of progressive creationism. In his book God Is; A Scientist Shows Why It Makes Sense to Believe in God (1978) he proposed the hypothesis of "successive creation" that “God has been at work ever since the universe began, performing a great number of creative acts at intervals” (pp. 197-198). In Creation and Evolution: The Facts and Fallacies (1985), he expanded on these ideas, supporting a form of “ancient creationism.” He was strongly opposed to young earth creationism, and refuted all its major arguments. According to Hayward the succession of fossil types is undeniable but it is not due to evolution; rather, to “successive acts of creation over a long period.” Of course his hypothesis of "successive creation" is not testable and is no different than just saying God did it.
