The other planets in our solar system are named for the classical gods of ancient Rome or Greece. Mercury, Venus, Mars, Jupiter, Neptune, Saturn and Uranus, their ancestors, and then Pluto.
So how did we get stuck with EARTH?
Sounds so common. Does anyone know? What should we be called if we could choose an ancient name?
I'd go with Gaia.
People were well familiar with the Earth long before they knew anything at all about planets. Some time after the discovery of
“stars” that wandered around relative to the fixed pattern established by most stars in the sky, came the convention of naming these wanderers*, or
“planets” after gods of Roman mythology. It was not until long after that that anyone understood that the Earth itself was an object comparable to the planets.

* In fact, the word
“planet” is derived from the Greek planētai, meaning
“wanderer”.
