The Goldilocks principle

Anthropic constants are scientific necessities for human life on earth. Astrophysicist Hugh Ross has calculated the probability that these and other constants (122 in all) would exist today for any planet in the universe by chance (i.e., without Divine design). Assuming there are 1022 planets in the universe (1 with 22 zeros following it), his answer is shocking; one chance in 10138, that’s one chance in one with 138 zeros after it. There are only about 1070 atoms in the entire universe. On earth, oxygen comprises 21% of the atmosphere. If oxygen were 25% fires would erupt spontaneously, if it were 15%, human beings would suffocate. If the atmosphere were less transparent, not enough solar radiation would reach the earth’s surface. If it were more transparent we would be bombarded with far too much solar radiation. If the CO2 level were higher than it is now, a runaway greenhouse effect would develop (we’d all burn up). If the level were lower than it is now, plants would not be able to maintain efficient photosynthesis (we’d all suffocate). This is just a sampling of the extreme precision which our universe (and especially the earth) was created with.  Without divine intervention, life would be impossible by scientific calculations. The God of the Bible is the one who made everything fit and work “just right.”
