Maoi of Easter Island

Easter Island (Rapa Nui) in Polynesia is famous for the iconic Easter Island Heads or Maoi. These Maoi are said top be built in honor and memory of former high priests. They would be built and transported across most of the island to be put on hills facing the sun. But weighing up to 14 tons and being up to 13 feet tall, it is a mystery to modern historians how they moved these megaliths with the technology available back then. Some ancient alien historians have speculated that these Maoi could only have been brought by ancient aliens. Another interesting fact about Easter Island is that this island is the only Pacific Island to hold historical evidence of a written language (similar to the Egyptian hieroglyphics).  This causes many Ancient Alien theorists to believe that ancient aliens helped this 

civilization in many aspects including written language. Though people will tell you creativity and regular technological advancements can account for the great Moai, the sudden disappearance of the population and their forests, as well as the only account of a written language in the Pacific Islands, the mystery of it all does make you wonder.
