He stretches the northern skies over empty space;
He hangs the earth on nothing.Job 26:7
Ancient cultures did not always know that the Earth was suspended in space. The ancient Egyptians believed it was supported by pillars. The ancient Greeks thought it was carried by Atlas. The Hindus held that it was resting on the backs of gigantic elephants, who were standing on a tortoise, who was standing on a coiled serpent swimming in a cosmic sea.
So how did Job—whose book that bears his name is perhaps the oldest piece of literature known to man—understand that the Earth is hanging “on nothing”? He could only have known through divine inspiration.
