Lemurians lived on this planet many eons ago. It was a pacific, prosperous and highly spiritual civilization.
They were aware that their world would be destroyed in the Great Flood. In an attempt to survive, some of them went to live underearth and others took the choice of big vessels...
Lemurian prophets knew that material things cannot resist the pass of time. In collective conscience they left a message they that the Great Flood occurs periodically and so it will come again.
This knowledge lays somewhere in our mind, but…can we remember the future?
