I said, "Or, here's another one. Suppose you have a very advanced civilization on, say, Mars." "Not Mars. No air, and too bloody dry to support life." "Don't interrupt, please," I said with mock severity. "This is a very old civilization and as the planet began to lose its water and air, it withdrew underground. Uses hydroponics and so forth, husbands its water and air. Isn't that what we'd do, in a few million years, if Earth lost its water and air?" "I suppose so," he said. "Anyway, what about them?" "Well, they observe how man is going through a scientific boom, an industrial boom, a population boom. A boom, period. Any day now he's going to have practical space ships. Meanwhile, he's also got the H-Bomb and the way he beats the drums on both sides of the Curtain, he's not against using it, if he could get away with it." Paul said, "I got it. So they're scared and are keeping an eye on us. That's an old one. I've read that a dozen times, dished up different." I shifted my shoulders. "Well, it's one possibility." "I got a better one. How's this. There's this alien life form that's way ahead of us. Their civilization is so old that they don't have any records of when it began and how it was in the early days. They've gone beyond things like wars and depressions and revolutions, and greed for power or any of these things giving us a bad time here on Earth. They're all like scholars, get it? And some of them are pretty jolly well taken by Earth, especially the way we are right now, with all the problems, get it? Things developing so fast we don't know where we're going or how we're going to get there." * * * * * I finished my beer and clapped my hands for Mouley. "How do you mean, _where we're going_?" "Well, take half the countries in the world today. They're trying to industrialize, modernize, catch up with the advanced countries. Look at Egypt, and Israel, and India and China, and Yugoslavia and Brazil, and all the rest. Trying to drag themselves up to the level of the advanced countries, and all using different methods of doing it. But look at the so-called advanced countries. Up to their bottoms in problems. Juvenile delinquents, climbing crime and suicide rates, the loony-bins full of the balmy, unemployed, threat of war, spending all their money on armaments instead of things like schools. All the bloody mess of it. Why, a man from Mars would be fascinated, like." Mouley came shuffling up in his babouche slippers and we both ordered another schooner of beer.
