The time had come when people needed proof that God does exist. Faith wasn't enough. Maybe it should have been, but it wasn't. And when science couldn't find any reason to suppose that the world was more than atoms and chance, humanity started slipping into chaos. The world needed a sign — scientific proof, the only sign it could accept — that God lives. The suddenly, as in biblical time, the sign was there: And for a day and a night the earth moved not around the Sun, neither did it rotate. And the laws of momentum were confounded. The Earth again took up its appointed course. And nothing otherwise was changed.
Except, of course, some of the ways of man.
