What if 2012 comes and goes and we see no Earth changes, no comets/asteroids, no pole shift, no nothing? what if everything just remains the same? what if 2015 comes along and still there are no changes.
What would that mean?
It'll be the same when Y2K came and went. Those who are determined that something should happen will find another cataclysm to look forward to.
Back in 1999 I read a statement by the Hopi People about the concern over prophecies for the end of the century. They said, nothing will happen, this is just the part of Earth's cycle when we see the sky signs. These signs indicate where we are in relation to major events in that big cycle. They continued to say, When nothing happens everyone will go back to living as they did before the dates prophecied, and when they have all forgotten, that is when the events occur.
To answer the question; If nothing happens, then nothing happens, and we are left with a long drawn-out demise for our race as we strangle it off the face of the earth anyway.
Better the earth changes do come then.
What if? Nothing happening is right now the most likely scenario.
When 2012 passes by, some new agers will start coming up with new dates while others will be claiming 2012 was indeed special in some subtle way.
