Visitors from space may have landed on our planet hundreds of times during the long, empty ages, while Man was still a dream of the distant future. Indeed, they could have landed on 90% of the earth as recently as two or three hundred years ago, and we could never have heard of it. If one searches through old newspapers and local records, one can find many reports of strange incidents that could be interpreted (解释) as visits from outer space. A winter, Charles Fort, had made a collection of UFO sightings in his book. One is tempted to believe them more than any modern reports, for the simple reason that they happened long before anyone had ever thought of space travel. Yet at the same time, one can’t take them too seriously, for before scientific education was widespread, even sightings of meteors (流星) and comets (慧星) gave rise to the most unbelievable stories, as they still do today.

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
