Easter Island - Indus Valley Scripts:

3). It is proposed that the script didn't exist before the arrival of the Spanish missionaries.

Response: The suggestion that Rongorongo didn't exist before the arrival of the Spanish is speculative and the evidence doesn't support this theory. Firstly, tradition states that it arrived with the first settlers, and at least two of the surviving tablets have a verified pre-Spanish origin (1) According to Thomson, Hotu-matua arrived on the island with 67 inscribed tablets or sticks (1889: 514). Though the number may be exaggerated, there is no reason to attribute the origin of the script to another source than that of the first settlers. If the script was only invented after the visit of the Spanish ship in the year 1770, as is maintained by S.R. Fischer (1997: 367), the inventor of the script would certainly be known by his historical name and there would be no need to replace it by a legendary name like Tuu-ko-Iho. Moreover, there are no similarities between the Easter Island script and the European, as is admitted by Fischer (1997: 375). Above all it is not a letter script and the Easter Islanders confessed that they had little understanding of their meaning since the elders were taken by 'Peruvian conquerors', suggesting an origin of great antiquity.
