Extraterrestrials in Meitei culture
The Meitei language PuYas, ancient scriptures of the Meitei civilization, describe the origin of Earth and life in ways that suggest the influence of extraterrestrial beings, referred to as the Laiyam (ꯂꯥꯏꯌꯥꯝ). Classical texts such as the Wakoklon Heelel Thilel Salai Amailon Pukok Puya and the Khamnung Ingal Leisaba describe the Earth as once being entirely covered in water, with life introduced through intervention from beings from the sky or outer space.
