Lemuria is seen as the first place on Earth where people lived in peace and were one with all life. I see that it existed at a time before Eden and that there were three Lemurias as Earth evolved into what it is today.
Lemuria lasted thousands of years, and the people there evolved. Perhaps Eden reflects the time when their innocence was lost, when they chose to be free-willed independent humans who made their own choices. Eden is often referred to as the time of the Fall. Was this the Fall from God’s grace? Humans were born with free will. How else were we to grow and learn? How can we grow without making errors that we can learn from?
