Well, let's put it that way. Mayan calendar goes in "cycles". Every time "cycle" ended and new started, a globad disaster occurred, almoust wiping away mankind. According to Mayans at least... Was it global flood, huge fires etc etc. So, rather then worring about what's ahead, let's look a bit backwards and have a glance of previous times the world ended.

Now, one cycle is about 4000 years. So the previous destruction of the world should have happened in about 2000 BC.

To make things more certain, let's take a previous end of the world, that must have happened around 6000 BC. Of that date, we have no written memories, but also there is no evidence of something global happening. End of the world usually should leave a quite large destruction front for us to discover, but nothing!

Same goes for 2000 BC. Nothing in particular happened. No global floods, volcanoes erupting, not even a single meteorite coming down. Nuttin' at all. My theory is that humankind was on the edge of extinction due to sheer boredom of nothing happening, but then someone invited beer and deck of cards. Thus, friday night poker saved the world! Or nothing really happened, take your pick.

So, if the next Mayan end of the world passes as unnoticed as the previous ones, we have nothing to worry about. Still, perhaps we could make a nice "happy end of the world party" and celebrate.
