I have just realised a better solution. I'm not sure if it means all what i wrote in last post is wrong or not. I'm abit short of time so this is just very quick.

It seems that a number of cultures had similar exagerated dates which indicates some sort of universal calendar (and it makes sense that there must have been some such), and it seems that that calendar must be above ("as above, so below") like maybe the Zodiacal/precessional Great year. It has already been shown that lots of cultures myths have zodiacal numbers encoded in them (72, 36, 2160, etc) Several have 12000/11000/10000 yrs/bc close to half a great year (13000 yrs). 9000/8000 yrs/bc is also common to a few, and in some is 3 cycles/ages/houses/signs. Many cultures around world had 4 world ages [and the zodiac has 4 quarter division].

Egypt: 11542 bc calendar coincides with Mexican/Assyrian/Indian; 11340 yrs Menes - Seti; Denderah calendar date between 10950 to 8800 bc; 9000/8000 yrs Atlantis.

Assyria: 11542 bc calendar coincides with Mexican/Egyptian/Indian.

Iran: 12000 yrs (4 x 3000 yrs) world; 9660 bc; 9000 yrs (3 x 3000 yrs) Ahriman; Zoroaster 5500 yrs before.

India: 11652/11500 bc / 12000 yrs; 8550 yrs (3 x 2850 yrs); 3102 bc; 2850 yrs cycle [2160 yrs zodical house?].

China: ....

Mayan/Aztec/[Mu]/[Otto Muck]: 11653 bc; 8238 bc; 8280 yrs (3 x 2760 y); 5125 yrs; 3373/3113 bc; 2760 yrs cycle [2160 yrs zodical sign?]; 751 bc [cf Numa/Hezekiah/Olympiad]. 4 suns [ages/cycles].

Tiahuanaco: "9550 bc"?

(Thats just a quick list of a few from A Tomas and from a few other refs, excluding many more need to add.)

The solution must be in this/that/there, but i not sure yet what the exact solution is, maybe one of you will solve it.

Some zodiacal or other possibilities for the 9000 yrs could be: 9000y ~ 3 cycles/houses? 9 milleniums ~ 9 ages/cycles/houses? 9 Patriarchs/ages?

more from the last 12+ hours:

The zodiac is Mazzaroth in Hebrew.

The zodiacal calendar is often said to start and/or end in Leo/Cancer (fire) and/or Aquarius/Capricorn (flood).

Leo to Aries would be either the 11000/12000 yrs (Daniel said Babel was lion/gold head) or the 8000/9000 yrs (Phaethon?). Atlantis sinking or war or founding 9000/8000 yrs would be either about a few houses before Aries & about 1 after Leo/Cancer, or else be Leo/Cancer.

Age of Pisces(-Virgo) 100/90bc / 6bc/ 1 ad/498ad - 1989/1994/2000/2012/2150/2654/2680/2817.

Age or Aquarius(-Leo) 1994/2000/2012/2062/2150/2595/2600/2680/2691/2700/2720 - 4000.

I do not believe the ages are literal dates. The earliest post-Flood age in [Egyptian,] Sumerian and Indian is said to be Taurus. So there is still some decoding of zodiacal to equivalent real times to solve.

Sorry i forgot one other thing:

9 x 1000 yrs Atlantis could alternatively/also possibly connect with 9/10 worlds/world-trees/trees Eddaic, 9/10 avataras Vishnu, 9/10 suns Yi (Chinese), 9/10 bows/arcs world Egyptian?
