I've been debating with myself about whether to post this or not, because that while it does interlock with some of my own beliefs, it also conflicts with them. I just finished watching a video which tries to connect crop circles with events prophesied by the Mayan calendar:
Hulu - Mayan Prophecies and Crop Circles - Watch the full movie now.
While I consider these things to be of pagan origin, I don't entirely dismiss them, because pagan beliefs do have a foundation which is kind of a negative aspect of my own. I would go into further detail about that, but this is about as far as I can probably go, without being chastised. Yet, I will say that evil often imitates good, and sometimes quite well, because while evil's understanding of good is not perfect, it does know enough to confuse the issues.
Whether a person puts any credence into these ideas or not, the video is quite interesting. I will close by saying that while 12-21-2011 is not going to be the end of the Earth, it could mark a point in time that will be of great significance, and be a prelude to the true end this era.
