The Mayans

The Mayans were awesome bunch of people. And they we're extremely smart too. They had technology and culture more advanced than anything else when they first began. But their history still remains, largely, a mystery. From what archaeologists could gather, the Mayan ideograms depicted the Mayan gods teaching them many skills such as irrigation, farming and astrology. Based on the fact that before civilizations like the Mayans, such as Babylonian and Sumerian civilizations, mankind was scattered, but much like apes and chimps, humans had small social groups. So how did civilization just pop out in a matter of years. Humankind went from discovering fire to building pyramids in a few hundred years.
This has led many skeptics to believe that we were visited by aliens many thousands of years ago. These aliens thought were thought to be the gods that were depicted in the Mayan ideograms. Think about that. Could it be that the Gods of the ancient civilizations were actually aliens that came to our planet, sowed the seeds and now wait to harvest them. Could it be that the reason the Mayan calender ends on 21st December 2012 is because they were told by their 'gods' that that would be when their time would come. Where their 'gods' would come to claim their prise.
Personally I do not believe in aliens, or more accurately said, I do not believe in the aliens that have been 'invented' by man. Maybe aliens do not have physical form. They could be a sentient force that sweeps across the universe. Or maybe even a non sentient organism such as a microorganism or virus that travels through space. Think about that too. Viruses are almost literally 'dead' in their crystalline form, but once in an organism, they become alive. They cannot reproduce but they can occupy a cell and multiply using that cells DNA code. Or something like that. Which is very weird an unnatural. It could very much be called 'alien' as no other organism displays similar characteristics.
Go back to the question at hand. What did the Mayans mean when their calender only went on to 2012. Most archaeologists agree that the Mayans believed that their Sun God, Quetzalcoatl, would return and engulf the world. Maybe thats not exactly what will happen. Let us explore the astronomic point of view. We can concur that the Mayans were either taught or talented in the field of astronomy. Back then, their high priests could predict eclipses of the sun and moon without any technology. And there is a myth that certain people, most notably Nostradamus, can gaze into the future by staring deeply into the stars (will discuss Nostradamus' later). So could the Mayans have predicted an asteroid or meteor or even a comet colliding with earth. If it did, that could spell the end of the human age, just as the dinosaur age had ended. A lot of freaky shit happens with our sun. And it could be something likened to a massive solar flare might wipe out every living thing in the Milky Way with intense radiation. Who knows. Until my next vision/revelation.
