Who were the lamurians?

The Lemurians, often associated with the mythical lost continent of Lemuria, are a part of various esoteric and spiritual traditions. They are typically described as an advanced civilization that existed in a now-sunken land in the Indian or Pacific Oceans, believed to be a source of wisdom and spiritual knowledge. In some interpretations, Lemurians are depicted as highly evolved beings with psychic abilities, often linked to the New Age movement. The concept of Lemuria itself originated in the 19th century and is not supported by mainstream science.
