CIA stole Sumerian tech, broke timeline on 12/21/12, hasn't recovered

Candace Owens just revealed the truth about the CIA’s top secret Project Looking Glass: Military and CIA whistleblowers alleged that they stole ancient Sumerian technology from modern-day Iraq. This ancient tech let them see possible futures and alter the timeline of human history. “They steal this piece of technology and they incorporate it into a computer, and suddenly they’re apparently able to predict future outcomes.” But all future timelines converged on December 21, 2012. After that, they could no longer predict or change the future. What changed in 2012? And why does it coincide with the Mayan calendar concluding on December 21, 2012? @RealCandaceO
