What giant’s body was used to create the world? Ymir’s body was used to create the world in Norse mythology.

Ymir was the primordial jötunn, or giant, who emerged in Ginnungagap, the void between icy Niflheim and fiery Muspelheim. In the Prose Edda, Odin and his brothers Vili and Vé killed him after the gods’ creation began.

The gods fashioned the cosmos from his corpse: his flesh became the earth, his blood the seas and lakes, his bones the mountains, his hair the trees, and his skull the sky. They made clouds from his brains and Midgard, the human realm, from his eyebrows. Four dwarfs—Norðri, Suðri, Austri, and Vestri—held up the sky at its corners.

Ymir is also called Aurgelmir in Old Norse tradition and is described as the ancestor of the jötnar. A common mix-up is treating him as a conventional villain; he is more accurately the primeval being whose death enables cosmic order.
