You can imagine that, Lee, but can you imagine how infuriating I find 
it? Suppose the alien asked you, "How come the righthand jutty-out 
bit of South America fits so neatly into the concave bite out of 
Africa, thousands of miles away?" and you airily explained, "Well, of 
course it must. Continents are like that." Never mind ocean floor 
spreading and plate tectonics; it's just obvious that it has to be 
that way. I don't think so.
