The Popol Vuh is very explicit. Although it brushed upon details of the beginnings of life, the whole gist of the manuscripts tell that life was already created and living in houses [even in palaces], it people were working the milpas in an orderly manner, according to the rising and settings of the Sun and the night sky. It told in great detail what occurred to that life that was already at a sedentary agricultural "sustenance" stage.An ordered society with rules and laws of religious observance [that had been ignored by many] was already based upon extensive star observations and calendar calculations.
Recently there was an article that came to the conclusion that comets that fell to earth, brought the origins of life about "how life appeared so quickly at the end of a period 3.8 billion years ago called the 'late heavy bombardment.'" [Found on http://www.independent.co.uk/news/science/comets-linked-to-beginnings of life explained by John von Radowitz in the e-zine The Independent.]
At first the astro-field said that the long ago disaster of 65 mya was caused by an asteroid. Now, it is caused by comets that fell to earth or at least when their debris did. The problem with either conclusion is that there has never been another disaster as the one described in the Popol Vuh; the narrators of the PV existed both before and after the event so they were able to tell the world exactly what had occurred from the time the nova first appeared to expand in the sky until its final explosive destruction that ended with the BIRTH of the Fifth Sun.
No one knows for sure the length of time that was necessary, since the calendars of Mesoamerica have been recalculated by many scholars who are attempting to fit that ancient timeline into our modern sky events. They have added the more complex math of Modern Calculus aided by computerize backtracking over the eons. The backtracking has been called "precession" that is supposed to be an approximate .05 per year change in the zodiac, as it is known today. The few accepted ancient calculations which have been identified, are not yet understood as idiomatic phrases nor is it understood why that aspect is even important.
The Popol Vuh has been ignored also, as only a myth. Yet it contains the whole story, one that has yet to be SEEN in its entirety by our astronomers who have not yet acquired the depth of information about the stars that the Maya, Aztecs and Inca had before the Conquest.
As it is, we seem to be having another precession in progress. . . since Daylight Savings has been moved by at least two weeks earlier (one each year) if not more. The climate is also changing,
What will happen this year is yet to be seen.
