I submit “Earth” is our planet's native name only in a few languages among thousands.![]()
I think it likely that most language-capable species would use the same word for the ground under their feet and for the planet they inhabit. So just about everybody's word for their own planet in their native language probably translates into English as “Earth” -- the same way many Native American groups call themselves “the people” or “the human beings” in their own language.
