A Neptunist is a scientist who subscribes to the Neptunism theory, which is an early 19th-century geological theory that suggests that the Earth's oceans, mountains, and valleys were formed by water and ice, rather than by fire and lava as proposed by the Vulcanists. The term is derived from Neptune, the planet known for its icy blue color and connection to water, making it a fitting namesake for the theory.
