朝鲜的学者主张古朝鲜的建国年代应该在公元前30世纪。一部分韩国学者也极力主张公元前2千年以前,古朝鲜就已经具有了国家形态。目前学界对古朝鲜国家建立的时期从公元前12世纪至公元前4世纪不等,其差异竟有800年之多,处于混乱的状态。 North Korean scholars argue that the founding of ancient Korea should be in the 30th century BC. Some South Korean scholars also strongly advocate that 2,000 years ago BC, ancient North Korea already had its own national form. At present, the academic circles established the countries of ancient North Korea from the 12th century BC to the 4th century BC, with the difference as many as 800 years, in a state of chaos.
