With apologies to Aesop:

Space and Time were disputing which was the stronger, when a planet came along wrapped in a warm ocean. They agreed that the one who first succeeded in making the planet bear life should be considered stronger than the other.

First, Space gathered atoms from the most distant parts of the Cosmos, but only succeeded in making a few lousy organic molecules, and at last Space gave up the attempt. Then Time gathered creatures from the future, when life had already evolved on the planet, and Space complained that Time had cheated.

And so Time snarled, "All right, smartie—you think it's easy to be me? You try it!" Then they changed places, and their contest continued.
