Easter Island, Chile

Located 3,700 kilometers off the west coast of Chile, Easter Island is the most mysterious place in the world. It is one of the world's most isolated inhabited islands and widely famous for its stone statues, of which there are more than 600. The stones look toward the sky, as if they are praying. No one knows who carved them or how they manage to finish those 20-meter-high statues with 90 tons of something. The most weird thing is that scientists use original stone tools to carve the stone statuses, but these stone tools cracked.
