Other very narrowly definded constants that point to an intelligent designer:
If the universe expanded on millionth more slowly, the universe would have collapsed on itself. If faster, then no galaxies would have formed.
A slight variation in the speed of light (299,782,458 meters per second)would alter the other constants and preclude the possibility of life on earth
If water vapor in the atomosphere was greater than what is it right now, tempertures would rise too high for human life. If less, then the green house effect would no hold enough heat for human life.
If Jupiter was not in its current orbit, the earth would be bomabarded with space material
If the earth crust was thicker, too much oxygen would be transferred to the crust to support lift. If thinner, there would be too much volcanic and tectonic activity to support life.
If a 24 hour rotation was longer, the temperature differences would be too greate. If shorter, spheric wind velocites would be too great.
The 23 degree earth lit is just right for life
Key Phrase:Only an intelligent designer could put so much in the balance for life
