If an age is around 2150 - 2160 years all we have to do is look at the last 2150 years and find the most influential century. In any 2150 years there can either be one change of age, or two if the change of age is now. If we are at the end of the age and the change is now, then the last end of an age should be 2150 years ago (ie (2nd century BC).
We probably do not have the detachment or objectivity to come to a conclusion about the end of an age now, but we certainly can make an objective analysis of the 2nd century BC. Unfortunately there is nothing in the 2nd century BC to indicate a change of the ages in that century.
Does anyone like to make the assertion that the 2nd century BC stands out head and shoulders above the other centuries over the last 2150 years? If so, we should discuss those events and developments in the 2nd century BC that make the 2nd century THE CENTURY. If no case can be made for the 2nd century we must (on logical grounds) discard the current times as the end of an age.
