The rocks cannot escape orbiting at incredible speed round the balls of fire, so they have to escort them towards an unknown place. And there are billions of balls of fire, trillions of rocks, and much more unknown stuff.
Around some of this traveling rocks exists a very thin layer of air and water. Its thickness: 1/20.000 of the diameter of the rock, thinner than the wrap of an apple. Real thin.
And in this layer survive some creatures. Not for long, because their lives last some decades, and they have been around for some 10.000 years while the dealings of this big, big space are counted in thousands of millions of years.
Also, they are feeble: in space, temperatures go in ranges of thousands of degrees, but switch the dial below or over a range of 50 degrees, and this creatures die very fast! And any change in this very very thin layer of air and water kills them also!!
Yet the creatures are brave (and blind too), because even when their existence, as we see, is hanging from a thread, and could be wiped out without a blip in the general machinery of things, these funny creatures think of themselves as the center of the universe.
