If scientists are divided on the subject--and they are--with some reputable scientists advocating the Mayan Long Count Calendar has some significance to what events will unfold and some other equally reputable scientists advocating the Calendar is being misread (and thus misinterpreted) and of no relevance to unfolding events, then it seems illogical and unreasonable for the ordinary nonscientific community to latch onto a dogma in favor of OR opposed to the significance and relevance of the Mayan Long Count Calendar. It seems to me that the only rational thing the nonscientific community can reasonably do is to adopt a wait-and-see attitude that will evaluate pros and cons as data and evidence for or against unfolds in real time.
It seems to me a dogmatic rejection or acceptance of that which expert scientists cannot positively disprove OR prove is an error in reasonableness, logic, rationality, and common sense: are there not many things that have been discovered with sound supporting evidence that have been surprising and unexpected? Yes, there have been, for instance, that prominences of the Sun oscillate; that neutrinos flip-flop back and forth between "flavors" (tau, electron, muon flavors) while in mid-flight; that the Cosmic Microwave Background hums in the key of B; that some bacteria live aqueously in poisonous clouds of hydrogen sulfide being completely without oxygen. We do well to be prepared to add more to the long list--longer than I can recall--of surprises silently surrounding us.
