Of course, if those three peaks in the Amazon jungle are really artificial pyramids, that's another matter. It is said that the highest is 200 meters, which is one third higher than the highest pyramid in Egypt. Archaeologists believe that from 12000 to 15000 years ago, an Indian tribe named Mogulala lived in these jungles. Some stone tools, pottery and other cultural relics unearthed today, as well as some inhabited caves in the virgin forest, have confirmed this.
