You're likely referring to the Moai, the iconic giant stone heads found on Easter Island. While it's true they have no bodies, they were originally carved as full-body statues, which have since eroded or been buried.

Here's how they were created:

1. Quarrying: The Moai were carved from volcanic rock found in the Rano Raraku quarry on Easter Island.

2. Carving: Using basalt tools, the Rapa Nui people meticulously sculpted the statues, often using platforms to reach higher areas.

3. Transport: It is still debated how the Moai were transported, but theories include:

* Rolling: The statues were rolled on logs, with ropes used to guide them.

* Dragging: The Moai were dragged on wooden sleds or platforms.

* Walking: Some believe the Moai were "walked" using ropes and levers, although this is highly debated.

4. Erection: Once at their destination, the Moai were placed on platforms known as "ahu."

Important Note: The Moai were not just heads, they were originally full-body statues with legs and torso. Erosion, earthquakes, and the passage of time have led to the loss of their lower portions, leaving only the heads visible.

The creation and transport of the Moai are a testament to the ingenuity and craftsmanship of the Rapa Nui people, and they remain a source of fascination and mystery to this day.
