xyco_fryx: Mayan are descendant of an ancient race of probably Lemurians ( as you can our dated history is only five thousand years ago, but others say it pre-dated back 30 thousand years ago). As you can see Lemurian were believe to travel by teleportation a long lost technology using only thr mind or psyche. I you can remember Enoch on The Bible (Old Testament that Enoch did not die because he ascended to what you call heaven (other esoteric figure call it another plane of existance)). Mayans are not barbarian as other book says in fact they are more technologically advance than you think same through as the Egyptians. Actually the cold about life is you must ascend first before you die or you will repeat another cycle of life in this earth.
The Mayan civilization for one, has not dissapeared it is still alive and well, the temples were abandoned but the language the culture and the people are still alive and well thank you very mcuh, who knows if the USA can say the same in one hundred years, I doubt it very much
The magnitude and nature of the Maya decline has been a mystery of sorts over the ages. One strong argument is based on some kind of ecological disaster. One dominate view is that intensive practice of swidden over one thousand years gradually resulted in the deterioration of the soil and its conversion into an artificial savanna. Thus, declining crop yields and the increasing labor involved with cultivation, combined with the growing needs of an expanding class of non-farmers, may have developed into a large amount of peasant unrest and dissatisfaction. An intensive increase of conflicts and warfare in what anthropologists call the Late Classic period also shows evidence of nutritional declines which reflect a rainstorm of problems in the Maya civilization. Widespread revolts combined with peasant movements to the frontiers of the empire left huge population vacancies that whatever was left of the ruling classes, were beyond their control. Thus with the arrival of Spanish expeditions, the Mayans were a depleted and unorganized group of people.
The magnitude and nature of the Mayan decline is clearly not the product of a single factor. Historians believe that some kind of ecological disaster was involved. One of the most convincing arguments is that the intensive practice of swidden for one thousand years gradually resulted in deterioration of soil and conversion of much of region into an artificial savanna.
