Plus in genesis it mentions light and dark on the earth being separate, which also implies a sphere. And that's how it looks when earth is viewed from outer space.
Given that the light is called Day and the darkness Night, I don't think that's a great interpretation.
Genesis 1, incidentally, does a great job of describing the Earth as a piece of land surrounded by an ocean, with a big dome called Sky covering it above from the waters all around.
