Earth, Wind, Fire, and Water. These elements typically refer to the concepts in ancient Greece of earth, water, air, and fire, which were proposed to explain the nature and complexity of all matter in terms of simpler substances. There is a fifth element, Aether, which describes the void or that which was beyond the material world.
While modern science has proven the ancient’s explanations incorrect with the discovery of atoms. There is still a similarity. The most commonly observed states of solid, liquid, gas, and plasma share many attributes with the classical elements of earth, water, air, and fire, respectively.
