fun fact, nobody would post anything in a year known as "2700 BCE or BC", bc the BC timeframe was created after Christ's birth. Therefore nobody in 2700 BC used the BC calender (and BCE is the same calendar, just people changed the meaning to get rid of any religion).
Greeks had their own calendar (i believe somewhere around 400 BC was the year 700 in Athens, but i could be mistaken
and the jewish calendar has stayed the same for 5000+ years.
