According to Steiner, people existed on Earth since the creation of the planet. Humans, he taught, began as spirit forms and progressed through various stages to reach today's form. Humanity, Steiner said, is currently living in the Post-Atlantis Period, which began with the gradual sinking of Atlantis in 7227 BC ... The Post-Atlantis Period is divided into seven epochs, the current one being the European-American Epoch, which will last until the year 3573. After that, humans will regain the clairvoyant powers they allegedly possessed prior to the time of the ancient Greeks (Boston).
