Do we take planet earth for granted? Or do we ever stop to consider just how wonderfully unique it is?

The surface of the planet Mercury (above) is scarred with meteorite craters. Many other bodies in the solar system are also. But meteorites hardly ever hit the earth’s surface because they burn up in our atmosphere before they reach the ground. Is it just by accident that our planet has this protective shield?


Despite all the speculation about 'extra-terrestrial life' these days, the fact is that very special conditions make life on earth possible — conditions which are not known to exist anywhere else in the entire universe! Scientists sometimes say that conditions on earth are “finely tuned”. So is this just a fluke — a lucky accident — or did some supreme intelligence finely tune it for our benefit? There are so many things which make earth unique that we need to seriously question the prevailing secular view that it just "happened" to be like this. Why is the earth situated in the "habitable zone" of our solar system? Why is the earth the right size to allow it to retain an atmosphere? Why is our atmosphere not poisonous like that of other planets? Why do we have such a convenient day/night rotational period, compared with 10 hours on Saturn to 243 days on Venus? Why do we have a large, unique moon which stablises the earth's orbit, and prevents it spinning too fast?(without the moon a day would last only 8 hours!)

Earth’s average distance from the sun is 93 million miles (150 m. km). This is within a narrow band where liquid water can exist — astronomers call it “the goldilocks zone”. Earth’s average temperature is 15 deg. C, compared with the average of 470 deg. C. for Venus and –50 deg. C. for Mars. Many scientists are urging us to cut carbon emissions, fearing a dangerous rise in earth’s temperature, which could cause serious problems.

NOT only is our planet specially suited for life to exist, it is also ideally suited as a home for intelligent beings who have a desire to learn more about the universe itself. That’s the view of astronomer Guillermo Gonzalez who with fellow-scientist Jay Richards in 2006 co-authored The Privileged Planet — since made into an excellent documentary film.1 As well as describing the “rare and finely-tuned array of factors” that make earth suitable for complex life, they explain that our position in the Milky Way galaxy itself is also crucial. We are in what they call the “Galactic Habitable Zone” — “the best overall location to be a successful astronomer and cosmologist.” Gonzalez and Richards point out: “Even though we’re near the mid-plane, there’s very little in the way of dust in our neighbourhood to absorb light from nearby stars and distant galaxies. We’re far enough from the Galactic center and the disk is flat enough that it doesn’t excessively obscure our view of the distant universe. We have access to a striking diversity of nearby stars and other Galactic structures, as well as a clear view of distant galaxies.”2
In the film, Jay Richards says:“I think you have to ask yourself, 'What if this convergence of factors didn't come about as the result of simply a cosmic lottery…or a mere fluke or luck? But, what if it's the result of some larger underlying purpose or design?
