2012 was just the start of a new 5000+ year cycle, and holy cow it's already been crazy, only 12 years in.

[sitindogmas]

2012 was the start, many tremendous events occurred in that time.

what a horrific crime against humanity to destroy almost all of the mayan culture. in the name of religion, so much knowledge has been lost all across the world. it makes me so sad.

[nevergiveup]

Why are we here in this life? Why do we die? What will happen to us after death??

It is such a shame that the Spanish destroyed the books and so forth of the Mayan Culture. Very sad.

I wonder if a thousand years in the future an archaeologist finds my kitchen calendar ended in 2023, he thinks that's the end of the world 🤪
Never made sense to me the Mayan prediction...

Some people believed the world would end in December 2012. 🤣 When it didn't end in 2012, then some wacky people started taking about the Julian calendar, and explained real Mayan 2012 was actually 2020. 🤣 (The Julian calendar thing was even reported in the news back in 2020.)

[savannahshepherd]

Simple in 2012 the age of Aquarius started 😅 just like how the bible talks about the age of the bull and ram ends etc. ancients knew astrology. 😊

[chha]

Yeah, the Catholics burned all of their books except for 4 of the codexes…😢 ridiculous
