You are all nuts.  I'm just as nutty as you.  Lost to calendars of tradition and heritage bias no human has ever had a fresh start or a chance at starting something new.  Your calander won't allow for it.   That is when a new calander begins.  When you interroductice a new collective reality radically different than normally thinking.  A new era.  A new time for the following to model from.  BC, AD, ??
