These all theories. But Edgar Cayce can be believed more than max muller who invented the "Aryan Theory".
And no his readings were not from OOB experience. As per him he accessed "what Hindus call Akashic records". He said his ability was by development of psychic ability in his past births particularly in a birth (incarnation) when he was left wounded to die on the war ground. We hindus call that source as third eye to honour which all hindu women put a bindi & all men used to put a tilak.
About Ram, yes Edgar Cayce has mentioned it in his at leats two readings such as "Ram in India" (reading 364-3). He could have given all his life's reading on Ram if he was asked. If he did not mention some names then it just means that he was not asked about them. And that true because Edgar Cayce was never asked any direct questions about history of India.
Also Edgar Cayce defines Atlantis as a continent between western Africa & Gulf of Mexico. Bahamas is a part of Atlantis. India was a totally separate land from the beginning of life on earth as per Edgar Cayce..
In a reading (readings for 364) he described that life started as five races about 10.5 million years ago on 5 lands viz Gobi, India, Capathia, Sahara, Atlantis. The same entity projected into different races & took the colour of the surroundings. Some lands like India had mixed colours due to its different surroundings as we go from north to south.
So, if we can see & realize that probably all the lands were destroyed (in the destruction that sunk Atlantis) except India which somehow managed to survive some of its civilization. Our ancient Hindu (actually Sanatan Dharam) scriptures tell the same story about destruction of lands when great lands went into the sea & new ones emerged.
