Demon

Demon (Greek: δαίμων, daimon) often denotes a malevolent entity in classical and modern cultures and religions. However, its Greek root, daimon, may not have necessarily carried any negative connotations. Daimon originally implied a spirit or divine power, possibly an equivalent to the Latin word numen, meaning "divinity", or a "divine presence", "divine will." At the advent of Christianity, Greek and Latin concepts were paganized, or essentially, demonized.

Origins
One of the most ancient written sources regarding a clash between good and evil is the Enuma Elis which recounts Mesopotamian cosmology. A great beast is described, known as Tiamat, who bears children to serve in her rebellion against Marduk (Babylonian), or EA (Sumerian). Tiamat was described as primordial chaos and sometimes identified with images of a sea serpent or dragon. The Enûma Elish states that Tiamat gave birth to dragons and serpents, among a more general list of monsters including scorpion men and merpeople. Such iconography had impressed Greek mythology as well as eschatology in Judeo-Christian theology. It is also a deep study in demonology as well as for developing support for the ancient aliens hypothesis.

Ancient aliens
Zecharia Sitchin, an advocate of the ancient aliens hypothesis, ran with these early concepts to promote his Tiamat hypothesis which states that Nibiru collided catastrophically with a planet, Tiamat, once located between Mars and Jupiter. This collision supposedly formed the planet Earth, the asteroid belt, and the comets.
