When did the name Earth come into being?

The name "earth" comes from the word "earth" in old English. When people don't know that the earth is a planet, the word "earth" only refers to the land where people walk. Later, the word not only refers to the earth under our feet, but also gradually refers to the whole world itself. As for when the word appeared, there is no way to verify it.

As for the Chinese word "Earth", it is believed that Matteo Ricci created it in the 6th century/kloc-0:

In the upper left corner of the Great General Geographic Map (1602), there is also a signed article by Matteo Ricci. The title of this article is "On the Distance of the Earth and the Geometry Larger than the Star of Nine Days? The word "earth" was found in this topic, which is the first example of "earth" in Chinese. In this article, Matteo Ricci explained the distance between the earth and several major planets and the ratio of the size of the earth to these planets. Japanese scholar Arakawa Kiyohide believes that Matteo Ricci's "Earth" was created according to the structure of the celestial sphere.
