When we hear the word ‘earth’, we immediately think of the planet or globe. But the primary meaning of the Greek word is land. This is how Young’s Literal Translation rendered it: “and the woman that thou didst see is the great city that is having reign over the kings of the land.'”
At the very least, when reading the Old Testament or the New, when the word earth appears in our modern translations, we need to question how the ancient audience would have understood the word and in what context.
