Interestingly, some scientists believe that it is our loneliness in the universe which makes us imagine that extraterrestrial life is possible. The universe is vast, never-ending. There are billions of trillions of stars, planets, meteors, comets. To think of this infinite amount of space with no intelligent life other than our own is not a comforting thought to say the least. In fact it is positively terrifying when one really thinks about it. And so, according to these scientists, we invent stories to fill up the void beyond our solar system, to imbue a lifeless universe with intelligent life and thus to make it seem a more habitable and friendly place to live.
