A person who believes in and promotes antisupernaturalism; someone who rejects supernatural explanations for natural phenomena.
From antisupernaturalism + -ist (one who practices or believes in). The term gained usage alongside the growth of scientific thinking from the 1700s forward.
Famous antisupernaturalists like Thomas Huxley actually invented the word 'agnostic' not to dodge the question of God's existence, but to be intellectually honest about what we can actually know versus believe.
