And the more scientists learn, the more the scientific facts suggest that the photosynthetic process, the complex structures required, and the complicated enzyme systems and cycles involved are the result of intelligent design. But concurrent with the growth process, again a change called aging inevitably occurs, so that continually some of the initial organizational excellence of the creature is being degraded. Ultimately the creature dies, and processes of decay soon destroy all vestiges of the ordered structures and systems which made up the living thing. The universal tendency of all things toward degeneration and decay is common to our experience. The works of man seem particularly vulnerable to this natural law of degeneration, regardless of how precisely and strongly they are constructed or how carefully they are maintained and protected.
Metals corrode, paint cracks and chips, wood decays.
Many kinds of change are coordinated with reverse processes so that a continually repeating cycle of change results. The water cycle illustrates cyclic change in nature. Radiation from the sun causes liquid water in the oceans to vaporize and disperse into the atmosphere. Wind currents carry the moisture laden air to high altitudes, where the reduced pressure permits the air to expand and thereby become cooled below the dew point so that the moisture condenses as snow or rain. Falling on the land, this condensation ultimately finds its way back to the sea whence it came, and so the water cycle is closed.
