I absolutely LOVE ancient history and archaeology. This story is fascinating to me!
The Easter Island statues were carved around 1250-1500 A.D. As excavators began to uncover the bodies of the statues, which had been completely buried, petroglyphs were discovered on several of the statues. The petroglyphs could reveal more about the Rapa Nui people who carved over 1000 statues that are scattered all over the island. If the bodies had not been buried by natural sedimentation or on purpose (no one’s really sure yet), the glyphs may not have been so well-preserved. Only about 100 of the statues bear the markings. Some people have speculated that the giant statues were made by an alien civilization, but I’m going to hazard a guess that the Rapa Nui people made them.
