To date Atlantis is a myth whose presence in our reality has never been substantiated. There are many mythological civilizations, ancient submerged cities, and research into ancient aliens that create the illusion of more advanced civilizations that came before us. As all is projected illusion in a simulation any and everything can be true.
The rise and fall of Atlantis may or may not have occurred in another timeline. I have met people who have memories of the fall of Atlantis, most often by natural disasters, when they hid information in crystals to be found in another timeline, perhaps this one. Most of these people believe they were priests who reincarnated in Egypt and now again in this timeline as we move consciousness from here to another level as the simulation closes.
