according to cayce readings it was the red race from atlantis

red race are the american indians, mayans etc

they did human sacrifice at the end of atlantis and this is why atlantis was desroyed by the elements of nature

also why karma it seems has turned many red race people into drunks

the races however don't really matter, all of us come from the one source, these meat bodies we inhabit do have different vibrations but outside of our meat bodies there is no white skin or race or red skin or race or black skin or race, these are material and shallow things we fight over that really mean nothing
