HERE ARE THE "INGA STONES". They are found up the Inga River in Brazil. The carving of the writing is 3.3 meters (about 10 feet) tall. Because of the symbols and the height of the writings, some linguists believe it was written by Giants. It appears to be written in the "Tupi Language", but they have not been able to interpret all of it yet. It is estimated to be 6,000 years old.
