What was the written language of the Polynesians called?

The correct answer identifies "Petroglyph" as the term most closely aligned with the kind of symbols or images created by the Polynesians, although it's important to clarify that Polynesians primarily used oral traditions for their culture and storytelling rather than a formal written language like those found in other civilizations. Petroglyphs are rock carvings created by removing part of a rock surface and can convey significant cultural and historical information. While it can represent forms of expression used by various ancient cultures, including Polynesian, it is not specifically a "written language" in the conventional sense.

In contrast, hieroglyphs refer specifically to the writing system of ancient Egypt, which used pictorial symbols for communication. Cuneiform was developed by the Sumerians in Mesopotamia and is one of the earliest systems of writing. Runes are characters from ancient alphabets used by Germanic languages, particularly among the Norse cultures. Each of these terms refers to distinct writing systems that do not relate to the Polynesian context in the same way as petroglyphs.
