Callum I have.Though admitatly there were a lot of things some of them seem to be a coincedence.Yes a lot seems acurate but how much of this is accually true,It could have been strecheed out over several years.And could have been edited through time.Have you ever heard of the cristian calendar?When Julieus Ceaser was at the helm the calendar was a new idea.People such as nobles,imperials,and holy men edited to suit superstition,government,and desire.
I liken this stuff to global warming: yes global warming happens but it has for aeons. You can research maps and graphs of the warming and cooling periods of the Earth over time for millions of years. We happen to have warming aided by our mistreatment of the Earth, currently, but she'll knock us down eventually.
2012 is a new era, a new period, and there will be more after it. I'm just glad that I get to live to see this all happen :) good or bad.
Global warming was already proven to be false, now their talking about an ice age. This climate thing is just rapid shifts up and down, 2012 has its own website for the discussion so I bet soon a mod will scold people talking about it.
However I must say, it is not a single date, but an era of shifts, its not the end of the world as a whole, just an end of the current state of the world and a total and drastic shift, I doubt anything shall be the same, but it is more than this hype makes it look, and is almost completely different than what people think it will be.
