Population Size of Atlantis?

[Parsons]

I have a little bit... but I am trying to find to correlate what Ra said specifically happened 10,855 (1981AD + 34) years ago: "The second and most devastating of the conflicts occurred approximately one oh eight two one, ten thousand eight hundred twenty-one [10,821] years in the past according to your illusion. This created an earth-changing configuration and the large part of Atlantis was no more, having been inundated. Three of the positively oriented of the Atlantean groups left this geographical locus before that devastation, placing themselves in the mountain areas of what you call Tibet, what you call Peru, and what you call Turkey."

So the timeline being off and the comet theory don't match up 100% to that.
