The world is full of things that represent either danger or opportunity, yet at any one time you aren´t concerned with most of them. Why? Because they are far from you. The tigers in countries across the ocean would eat you in a minute if they could, but you needn´t worry, because they are nowhere near you. This is the gift of space: almost everything is far away from us and can be ignored for the time being.
Imagine a world containing an enormous variety of objects without the organization of space. Anything might impinge on anything else at any time. There would be no distance to keep things separated.
