My humble opinion...There is no way all of the ancient advanced cultures dated this time ( or around it) as the end of the age. It is so much more than just MAYAN. I do believe that this is the end of the age. That said, funny little thing about this tribulation period that was also foretold would come. It is a given time period. An extension if you will. A time that will try men's souls to see WHO they will call god. Holding open a "gate" a given key to mankind to do so would do the job in my opinion. I think that is exactly what is happening. This extra time is short...hold fast and beware of what and who brings the peace and safety.
