In this wide-ranging conversation, philosopher of science Dr. Stephen Meyer and Rice University chemist Dr. James Tour contrast biological evolution with the more complex challenge of chemical evolution, where modern science still struggles to explain how nonliving chemicals could give rise to life. They critique early experiments like the Miller-Urey experiment, emphasizing that producing basic molecules is far from creating life itself. Meyer and Tour also argue that as scientific understanding deepens, the complexity of life’s origins becomes more daunting, raising both scientific and philosophical questions about the adequacy of the current mainstream scientific explanations and theories for the origin of life.
