Conspiracy theory of the week: Stonehenge to Easter Island, a person?

As you know, Stonehenge is most famous for its mysterious origin. It was built by a culture who essentially left no records of themselves or how they moved the large slabs of stone, or why. Cut to halfway around the world, we find ourselves on Easter Island, a mysterious set of land with giant stone heads sticking out of the ground. Unbeknownst how or why they were built, there are many theories as to what it is. Now we travel to Uruguay, where a giant hand is known for reaching out of the desert, and no one can figure out why. Could there be a giant stone man sitting in the center of our planet? Draw your own conclusions.
