Well, baktuns are known with another name or by another way in other cultures. It's the second I mention it and you come with this same argument. I don't care if the majority or the literates in history don't regard it as an important reference for the cycle of eras, I find it interesting enough and from what I gather, it matches the social, economical, hystorical events described about each baktun. I said loads of people are preparing for the changes that will come not based on the baktuns, but by any other way they know about the end of this cycle.
