Evil Alien Writing?

Rongorongo

They are a system of glyphs and were discovered in the 19th century on Easter Island. These inscriptions were carved onto two dozen wooden objects with weird shapes of distorted humans with large eyes on the outside of their heads. Some theorize that this shapes depict evil non human creatures. Experts have yet to decipher what the symbols mean due to the fact that when they were found they had been heavily weathered, burned, or otherwise damaged, None of the objects remain on the island. They are all scattered in museums and private collections.
