Astrological records by the Maya are at least 4000 years old. And they did not predict the world to end. Their legends say that this world will not end at all (Contrary to the others, which had been destroyed by the creator god because he used the wrong material to create humans).
It's a little bit like the 640k memory quote from Bill Gates, which is something he did never say (one can't seriously expect him to be that narrow minded anyway). Or like the flat earth worldview myth. The earth being probably a big ball is widely recognized amongst scholars for many centuries already, and even before christ. The Greeks already were able to calculate the circumference of the earth quite accurately (by using the sun and the distance between two places which I can't remember yet).
What is often mistaken as en ending world is an ending Maya calendar I think. As far as I know, if a calendar ends a new one begins. No end of the world. But my knowledge of this is minor. All I read is that the Mayas predicting the end of the world is a myth.
The big bang theory, at best, is a simplistic and somewhat inaccurate portrayal of how things really are.
But amongst others it's the most accurate portrayal I think, based on observations. Most people I've heared criticising modern science and the big bang theory do not present an alternate rational theory.
It won't be possible for present-day humans to fully understand the genuine nature of the cosmos, even with the help of extra-terrestrials from another dimension or from outside our universe. Our brains are too limited. Too simple.
Simplicity is not what you discover when you look into the human brain and research it. It is one of the most, if not the most complex object in the universe. The human brain contains the capability to realize, analyse, understand and utilize the environment in which it is living, and even that one in which it is not living (space). It is likely that our brain contains all informations required to analyse and understand
everything, if cultural and scientific progress permits. It's the time which is missing, not capabilities.
There was an era during which people dreamed about flying, but which was widely expected to be impossible in any case. And flying to the moon? People would have told you completely insane for believing in something like this. In 1936 the New York times still did write that a rocket will never be able to leave the Earth's atmosphere. While I am typing this on a machine which has a chip that is faster than any organic cell or organism, there is a permanently inhabited space station which orbits above my head every ~95 minutes, whilst there are thousands of airplanes in the lower layer of the stratosphere at the same time continuously, consisting of metall and flying with a speed just a little bit below the speed of sound...
