It is not just the universe that bears evidence for design. The earth itself reveals such evidence. Frank Drake, Carl Sagan, and Iosef Shklovsky were among the first astronomers to concede this point when they attempted to estimate the number planets in the universe with environments favorable for the support of life. In the early 1960's they recognized that only a certain kind of star with a planet just the right distance from that star would provide the necessary conditions for life.12On this basis they made some rather optimistic estimates for the probability of finding life elsewhere in the universe. Shklovsky and Sagan, for example, claimed that 0.001 percent of all stars could have a planet upon which advanced life resides.13 While their analysis was a step in the right direction, it overestimated the range of permissible star types and the range of permissible planetary distances. It also ignored many other significant factors. A sample of parameters sensitive for the support of life on a planet are listed in Table 1. Table 1: Evidence for the design of the sun-earth-moon system14 - 31 The following parameters cannot exceed certain limits without disturbing the earth's capacity to support life. Some of these parameters are more narrowly confining than others. For example, the first parameter would eliminate only half the stars from candidacy for life-supporting Systems, whereas parameters five, seven, and eight would each eliminate more than ninety-nine in a ...
