1. Removals: Jesus Christ (#1), Confucius (#2), and Buddha (#16), are three Aggregate non-existive religio-mythology figures removed from the list, as they were not individual “people”, per se; the first and third, i.e. Jesus and Buddha, being religio-mythology figures, derived largely as extensions from the Imhotep-constructed Heliopolis creation myth theory, the second, i.e. Confucius, being largely a Chinese proverbs attributed aggregate figure, arguably non-existive, similar to other mythological figures, such as: Abraham, Moses, Mohammed, Lao Tzu, etc. (Ѻ)
