I am open to the idea of 2012.
Though I don't exactly think the Mayans have predicted correctly unless it's to do with why I think it could happen. The reason as to why I think the world may end, or may just be undergoing catastrophic events, is that lately there have been a serious of natural disasters around the world. What if it keeps happening at the rate it is? By December next year, there will be a lot of damage done around our globe. Since January we've had really bad floods and cyclone Yasi here just near where I live, earthquakes in Christchurch, the tsunami that hit Japan, various tornadoes over near Florida etc. in the US and now the Joplin tornado. I'm sure that's not all. So.. if mother nature keeps hitting the planet with this sort of weather, no doubt there'll be great damage some time in the next 18 months. Though I do know that 2012 may not be world's end (as much as it may be), or that these natural disasters will keep coming. Anything can happen.
However, I don't believe in the rapture or the apocalypse.
