This has developed into an urban legend. 2012 is also the return of the Anunaki of Sumerian legend on the same date, with their planet Nibiru which is on a long elliptical orbit which is suppose to be only visible from the South Pole.
Planetary slavery and destruction from reptilian aliens will result on that date. Aliens who have genetically engineered us 10000 years ago when they ruled over us.
So I guess I should cash in my 401K? (sarc)
It might make a good horror movie.
My theory is that is the date the people at the CERN Large Hadron acclerator in France will crank up and swallow the Earth into a man made black hole.
The Anunaki have taken the White House.
They only ruled over certain parts of the Earth - primarily the middle east.
Neither were reptilian species. The Reptilians are suppose to rule a vast empire beneath the Earth.
