Why isn't the earth called water polo?

As we all know, the earth we live in is a planet surrounded by water, and more than 70% of the earth's surface is covered by oceans. But why don't we call it water polo when we name the earth? Then let's reveal why the earth is not called water polo by constellation knowledge. Let's have a look!

Why isn't the earth called water polo? The total surface area of the earth is about 56.5438 billion square kilometers, the water area is about 36.65438 billion square kilometers, accounting for 765.438+0% of the total surface area of the earth, and the land area is about 65.438 billion square kilometers, accounting for 29% of the total surface area of the earth. Seen from space, the earth looks like a water polo, which is blue, so it should be called water polo.

But in ancient times, people lived on land, and the range of activities and observation was small, so they could not realize the whole picture of the earth. Coupled with the backward navigation technology in ancient times, they didn't understand the vast ocean area at all, so they named the earth not water polo, but the earth. When giving this name, people not only think that the land of this world is bigger than the ocean, but even think that the land will always be flat. The earth is the third planet in the solar system from the inside out, and the earth-like planet with the largest diameter, mass and density in the solar system.

Earth is the only name that doesn't come from Greek or Roman mythology. The word earth comes from old English and Germanic. In Roman mythology, the goddess of the earth is called Tellus, which means fertile land (Greek: Gaia, mother of the earth).

The Chinese word "land" comes from the preface of "The Whole Map of Caoshan Land and Sea in Guizhou" written by Guo Wei, a missionary in Ming Dynasty, which says: "Li Sheng said that the sky has two poles, and the earth has two poles, which is only 360 degrees, so there are celestial spheres, lands, meridians and latitudes. The east, west, north and south of the land are all 90,000 weeks, with a land thickness of more than 28,600 Wen (Li). There are teeth living on both sides, and there is no distinction between them. This is something that China has never heard of. "

There is also a saying that the word "land" appeared in the Ming Dynasty because western missionaries introduced western geocentric theory to China at that time. They think that the earth is a completely different product from other planets, and the earth is the center of everything, so they try to separate the earth from other planets, so they create names different from other celestial bodies to call the earth.
