Question

why does earth called earth​

Answer 1

Answer:

The answer is we don't know. The earth name is derived from both English and German words, which mean ground.

Answer 2

Etymology. Unlike the other planets in the Solar System, in English, Earth does not directly share a name with an ancient Roman deity. The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil. It became eorthe later, and then erthe in Middle English.
