I mean, like calendar's we have today, we can make a new one.
and we can also turn pages of our calendars, maybe there's another set , but then again
i don't really care or know much about the Mayan calendar and all that crap.
It was just something cool i found and wanted to share; as i hadn't found it online but major nerds using thousands of equations to decode something. I kept it simple :P
Its just the human mind wrapping itself around its own theories. You can take anything and warp some numbers around, and pull some equation out of your ass and get the same thing. Its been around for a long time too.
Id be more worried about aliens than the world simply not working anymore.
