Proponents of intelligent design claim that the universe, Milky Way Galaxy, Solar System, and earth are specifically designed by an intelligent agent for habitation by human beings. Others say that such claims amount to a God of the gaps argument, since scientists do not yet have answers for the apparent design of the universe. If the skeptics of intelligent design are correct, then science should be finding that we do not occupy any special place in the universe. However, a new study disputes the idea that earth's moon is just an ordinary moon.
Formation of the Moon
Scientists now know that the Moon was formed by the collision of the small planet with the earth, which resulted in the ejection of 5 billion cubic miles of the earth's crust and mantle into orbit around the earth. This ring of material, the theory states, would eventually coalesce to form the moon. In addition, the moon is moving away from the earth (currently at 2 inches per year), as is predicted by the theory. If we calculate backwards, we discover that the moon must have formed just outside the Roche limit, the point at which an object would be torn apart by the earth's gravity (7,300 miles above the earth's surface). A collision which would have ejected material less than the Roche limit would have formed only rings around the earth. Computer models show that a collision of a small planet with the earth must have been very precise in order for any moon to have been formed at all.
The new study
When a moon is formed by the kind of collision that formed Earth's Moon, dust would have been blasted throughout the solar system. Astronomer Nadya Gorlova of the University of Florida, Gainesville, decided to study newly forming stars to determine what percentage might have a moon that formed through one of these massive collision events.2 In examining 400 newly formed stars (30 million years old), only one shared characteristics that would suggest that such a large collision had occurred, which might form a moon. Of course, the probability that the newly formed moon would orbit an earth like planet within the habitable zone would be much less likely.
Although no earth-like planets have been detected yet, it is likely that they do exist. However, it is unlikely that such earths would have a moon the size of Earth's moon, since such a pair could not coalesce together, nor could such a moon be captured by a small planet like the earth. Therefore, the only means by which such a moon could form would be through a collision event early in the history of stellar formation. In the first study to examine the probability of such a formation, a new study shows that only one in 400 new stars might have formed such a moon through a collision event. Why is it important how the moon was formed? Without such a large moon, earth's rotation axis would be unstable, swinging through 90� or more, resulting in extremely variable climate over its history. In addition, the collision event itself blew off earth's heavy early greenhouse atmosphere, which allowed the planet to retain its water for billions of years. The removal of much of the earth's crust also allowed the earth to retain its tectonic activity for billions of years, which allowed for the existence of both land and ocean. Without such tectonic activity, earth would have become and remained a waterworld. For more information, see The Incredible Design of the Earth and Our Solar System. Astronomy and cosmology continue to provide evidence that the earth is not just an ordinary planet in an ordinary solar system.
Rare Earth: Why Complex Life is Uncommon in the Universe by Peter D. Ward and Donald Brownlee
A secular book (2000) that recognizes the improbable design of the earth. Paleontologist Peter D. Ward and astrobiologist Donald Brownlee examine the unusual characteristics of our galaxy, solar system, star, and Earth and conclude that ET may have no home to go to. Surprisingly, the authors conclude that the amazing "coincidences" are the result of good luck and chance.
A classic book by astronomer Hugh Ross on modern Christian apologetics and science, (updated June, 2001). Dr. Ross presents the latest scientific evidence for intelligent design of our world and an easy to understand introduction to modern cosmology. This is a great book to give agnostics, who have an interest in cosmology and astronomy.

General Relativity: Well-Tested and Standing Strong
General relativity represents the best description known to humanity of how the universe behaves. It explicitly incorporates the idea of constant (in both space and time) physical laws. It also generically predicts a dynamic nature to spacetime such that space expands and the whole universe begins to exist. Such results comport well with biblical descriptions … Read more

Do ENCODE Skeptics Protest Too Much? Part 3 (of 3)
In light of the belief that the human genome is largely a genetic junkyard, the ENCODE Project’s phase two report that 80 percent of the human genome consists of functional DNA elements is an astounding announcement—and it is not without detractors. In part 1 of this series, I collated the criticisms published by ENCODE … Read more

Do ENCODE Skeptics Protest Too Much? Part 2 (of 3)
Several recently published scientific papers strongly critique the results of the ENCODE Project’s second phase—which reveal that at least 80 percent of the human genome is functional. In this installment of a three-part response to those critiques, I examine two of the most significant challenges: (1) The ENCODE project used a faulty definition of function; … Read more

Do ENCODE Skeptics Protest Too Much? Part 1 (of 3)
When the ENCODE Project reported that at least 80 percent of the human genome consists of functional sequences, they forced a radical revision of scientists’ understanding of human genetics. But recent scientific papers have called this conclusion into question. In this three-part series, I collate and describe the criticisms published by ENCODE “skeptics” and then … Read more

Does Evolution Explain Converging Ion Channels? Part 2
Recent studies of ion channels have dramatic implications for Christian apologetics.

Does Evolution Explain Converging Ion Channels? Part 1
If evolutionary theory is true, scientists should not expect to see biological systems and features “repeated” in supposedly unrelated organisms—yet nature is replete with occurrences of such convergence. For example, recent studies of ion channels found similarities between mammalian brains and potatoes. These findings have dramatic implications. While they are surprising to anyone presuming naturalism, … Read more
