Apparently the age of earth is 4.5 Billion years old?
The earth is infinitely old. time is a continuum, a cycle, that never ends. its the only 'constant' in the universe.
Earth has been here forever. earth is life. its a living thing

As you can see time is in reverse, hence how the mayans predicted these dates.
more info on the calendar but the dates are a bit off...

The World "Ends" from a combination of WIND, FIRE (from the sun exploding), WATER and EARTHQUAKES. :O :O
So the end of the calendar, is the start of a new cycle, the beginning of life it self, and the birth of a new god. the big bang in science terms.
isnt everyone excited? we are all going to be at peace and in nirvana/bliss
