Isaac Asimov wrote a really great essay about this, in which he pointed out that some people thought the Earth was flat. And it is flat, on a local scale. Then people thought it was round. And it is round, just not exactly. Then it was considered an oblate sphere. And it is an oblate sphere - just not exactly.
