If you want a rather crazy theory, which also takes the DNA into account:
The "original" human had the ability to use the full potential of his body, including the energetic system of the body and the brain. His DNA had 12 strangs and he was a telepathic being. The human potential was nearly unlimited (which was a good thing, since humanity was "lead" through their common spirit), but through the course of the early history of human kind (and I mean early as in "before the flood") he was genetically manipulated to be kept under control.
Thus he lost his telepathic abilities, which caused great confusion since language is just a inferior way to communicate and invokes lots of misunderstandings (babel, anyone?) and also lost his awareness of the higher realms of existence. At least the majority did.
By denying the knowledge of the past and presenting themselves as the true creators of human kind, those manipulators managed to lead humanity into a mind-set which lets them disempower themselves because they simply dont see the truth and accept lies as answers to their questions.
By now, humanity is in the process of reawakening. More and more people discover that there is more behind what is usually referred to as "reality" and start to explore their inner consciousness - which ultimately leads to rediscovery of ones true nature and potential.
And if you want to know what 2012 has to do with this: Imagine the whole planet being bathed in a stream of energy, reactivating the human DNA.
In the cosmic cycle this represents the moment of a forced global awakening and possibly ascension to those higher realms. Unfortunately, those manipulators have done a pretty good job so far and if you are in denial of anything behind materialism, your consciousness might not be able to cope with it.
Hard to explain, but maybe you could imagine the whole planet suddenly TRIPPING BALLS on LSD. Those who are open to it and got a good mind-set will embrace the experience and grow with it - those who oppose it will suffer and probably break down.Yes
, I honestly believe this. Sounds rather crazy if you read it the first time, but I've been gathering informations since several years, connecting dots and making experiences within myself - and I havent found a single thing, which doesnt fit it. In the common belief-system, there are so many holes which are just explained as anomalies or "we dont know yet, so we dont care".
If anyone is interested in some more details... read this!
Its really worth it.
