The Earth, also called the Human World (人間界, Ningen Sekai), is a planet created along the stars and planets. It is home to millions of species of life, including humans. It is the main setting for every Yu-Gi-Oh! series, and all of the protagonists call Earth home. It is revealed in Yu-Gi-Oh! ARC-V that there are many parallel Earths spread across the multiverse. One alternate Earth resides for each method of Summoning introduced except the Pendulum Summon, and the Duelists who survive on those alternate Earths utilize the Summoning method associated with their dimensions.
The Earth appears a low-energy world enabling a proliferation of organisms for plants and animals.
The modern English noun earth developed from Middle English erthe personified as a goddess in Germanic paganism (appearing as Jörð in Norse mythology, mother of the god Thor). In general English usage, the name earth can be capitalized or spelled in lowercase interchangeably, either when used absolutely or prefixed with "the" (i.e. "Earth", "the Earth", "earth", or "the earth"). Many deliberately spell the name of the planet with a capital, both as "Earth" or "the Earth".

The Numeron Dragon who was the first being to have existed, used it's power to create the universe, however this took all the power it had, nearly killing it. With it's remaining power, the dragon shed a single tear which contained all of its emotions and knowledge. When the universe began it split into darkness and light. As the light vanished soon, the darkness would fill the universe and create everything in the world, including life.
The tear the Dragon shed took the form of a card, the front represented the Earth also designated as the Human World and the Duel Monsters Spirit World, while the darkness was the World of Darkness. Eventually, the stars and planets were born, including the Earth, where the humans stood at the top of all creations. The card eventually impacted on the Earth, resulting in the Moon being formed. Inevitably, the humans discovered the Duel Monsters, therefore, it became a touchstone to test their souls.
10,000 years before the start of the series, a perfect city known as Atlantis existed isolating it from the rest of the world. It was inhabited by Duel Monster Spirits and humans, who coexisted peacefully. They were said to have known nothing of violence.

He went to a temple and requested the assistance of the Duel Monster Spirits, which they agreed to lend. After a battle known as the Battle of the Stone Wasteland, The Great Leviathan was defeated and sealed away by Ironheart's army. Before his death, Ironheart sealed the doors to the Duel Monsters Spirit World, leaving behind their spirits scattered across all the world. Some were left in the Egyptian pyramids, the Greek temples, the Aztec pyramids, the Egyptian mastabas. Dartz survived, and began gathering souls to revive The Great Leviathan to destroy and reconstruct both the Earth and the Duel Monsters Spirit World in his own image.
