Our Fine-Tuned Universe Strongly Suggests the Necessity of an Intelligent Creator

The famous Fred Hoyle was an adamant atheist until he realized that the basic physics and chemical structure of the universe clearly required fine-tuning:

Suppose you were a superintellect working through possibilities in polymer chemistry. Would you not be astonished that polymers based on the carbon atom turned out in your calculations to have the remarkable properties of the enzymes and other biomolecules? Would you not be bowled over in surprise to find that a living cell was a feasible construct? Would you not say to yourself, in whatever language supercalculating intellects use, "Some supercalculating intellect must have designed the properties of the carbon atom, otherwise the chance of my finding such an atom through the blind forces of nature would be less than I part in 10^40000." Of course you would, and if you were a sensible superintellect you would conclude that the carbon atom is a fix.... A common sense interpretation of the facts suggests that a superintellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature.
