This is a funny question and you should have your answer by now. The Mayans were wrong. Nothing has happened and those who predicted the end of the world are wrong once again.
Here are few points to consider:
1. As long as people have been around, there have been those who predicted the end of the world. An example is Harold Camping, who predicted the end of the world this year on October 28.
2. In difficult times or times in which great changes take place, there seems to be people or groups who are very apocalyptic.
3. Based on these two points, there will be many more predictions in the future.
Nope it hasn't! We are still alive...well...most of us.
