Why is Earth the only planet that isn named after a Pagan God?
You are incorrect. The word “Earth” comes from the Old English word “eorthe”, which refers to the region that came between the world of the gods and the underworld. It is just the word English-speaking people use. When the planets were named for the Roman gods, Earth was known as “Terra”. This was the name of the Mother Goddess, equivalent of the Greek Gaia or “Ge”. Indeed in many languages the word for “Earth” is “terra” or a variant of this Latin word. That’s where why we describe aliens as “extraterrestrials”. In Greek, the planet is named Ge (Γῆ) for the Goddess.
