Paleo-scientists study lost places, times, and species. Similarly, lost, hidden knowledge and places are important to occultists. By the nineteenth century, little territory on earth was left unexplored; however, to the occultist, submerged, subterranean, extraterrestrial, and astral planes were still available for exploration. Unlike archaeologists and historians, who have a limited archive of historical material to recreate human history, occult groups rely on clairvoyance, channeling, and psychic readings. By accessing psychic abilities, occult groups can draw on unlimited historical resources to complete the record of human history. For those people involved in occult history, the history of humankind is spiritual, not biological, and goes back to creation; for scientists, creation begins with fossils in the Quaternary period, about two million years ago.
It is obvious occultists try to provide a full record of human history, not part of it. Madame Blavatsky argued that civilizations are similar because they are the descendants of a single ancient one. For example, it is not a coincidence that there is an outward similarity between the pyramids in Mesopotamia, Egypt, China, India, and Mesoamerica. Blavatsky believed all pyramids were the result of a prior civilization. The Lemurians, and their Atlantean ancestors, are responsible for the evolution and achievements of humans.
