They found more of those calendars and in those there are dates some 7000 years onwards, that was published long time ago, but for some reason that discovery has not gained as wide spread as older discovery, maybe people want to believe world to end or something. It is only 6 days until religious celebration this year, before that is even one weekend, so they don't have much time to work on update for sure.
I suppose that really depends on whether a car is painted or wrapped nowadays .............but I agree.
How would you be able to tell it if your world had just ended and hence you wouldn't even exist anymore!?!
Wow! That really is quite amazing... those guys did/do an awesome job, made it look really easy. Nice post Tim.
