A symbol cannot be “invented”, created artificially, as it reflects the Highest Truth. The perfect Universal Symbol is so comprehensive that it is able to meet the needs of different eras, religions, cultures and civilizations.
Time did not radically change the structure of symbolism. Whatever the nature of the origin of the symbols is, modern mankind got them not only completely formed, but already systematized.
The same symbols exist in all ancient cultures: in Ancient Egypt, Sumeria, India, China, Africa, in pre-Columbian America… And everywhere they have similar semantic meanings, which indicates their common origin from the same source.
