Invalidated fake A.D. anno domini has no B.C. world history valid foundation.

After 509 BC  coup.  The invalid existence of fraudulent calendar by European sodomite is explained here: 

B.C. refers to "Before Christ," (explain what BC 200,000 era was like before Christ), and the initials, A.D., stand for Anno Domini, which is Latin for "In the year of our Lord."(explain in the year of our lord).    This system was devised by a monk in the year 525. A more recent system uses B.C.E. which stands for "Before the Common Era" and C.E. (what is 'common' era)     

Bede the Venerable used the expression "anno igitur ante incarnationem Dominicam" (so in the year before the Incarnation of the Lord) twice. The B.C./A.D. system gained in popularity in the ninth century after Holy Roman EmperorCharlemagne adopted the system for dating acts of government throughout Europe....Oldest written document ever found in Jerusalem discovered. Summary: A tiny clay fragment -- dating from the 14th century B.C.E. -- that was found in excavations outside Jerusalem's Old City walls contains the oldest written document ever found in Jerusalem, say researchers in Israel.....   Dionysius Exiguus. Roman scholar and theologian Dionysius Exiguus (c. 465 A.D.-c. 530 A.D.) is best known for his creation of a calendar that led to the modern Gregorian calendar. From his calendar stem the designations “B.C.” and “A.D.”Dionysius is best known as the inventor of the Anno Domini era, which is used to number the years of both the Gregorian calendar and the Julian calendar. He used it to identify the several Easters in his Easter table, but did not use it to date any historical event.
