Accordingly George Cœdès discoveries, Number Zero was found in 1891 on a stone inscription in the ruined temple at Sambor on the Mekong River, today Kratie province. The inscription began: “The Çaka era entered year 605 on the fifth day of the waning moon.” It was this number, 605, that was so overwhelmingly important. Because we know that the Çaka dynasty began in AD 78, we can date the artifact exactly: to the year AD 683. This makes the “0” in “605” the oldest zero ever found of our base-10, “Hindu-Arabic” number system.Number Zero were used in Chaka era began in AD78, and the inscription was made AD683 which is shown that the Khmer people was the first inventor of number Zero and placing it a full two centuries earlier than the Indian Zero. It existing proved Zero was not invented in Europe or Arabia.
