Some one at Bungie was probably playing with their ring and looking at the inside of the ring and said, Hey, wouldn't it be cool if there was like a planet's surface on the inside of a ring?.
And the rest, as they say, is history.
Oh, and the name Halo has to do with religious stuff and the ring is a religious icon to the Covenant.
