The earth spins in perfect motion, not too fast or too slow. Any closer to the moon and there would be great tidal changes causing another great Flood. The sun is perfectly distanced from the earth: If it was much closer it would bring unbearable heat; much further and it would bring freezing temperatures.
Trees produce oxygen, which gives life. Without trees there would be no life. Take away water and there would be no trees (or any other life for that matter). Take away the sun and there would be no life. Add too much water and everything would drown. Without clouds and rain there would be no natural distribution of water throughout the earth.
We have seasons, cool for a little bit then warm again. Dirt is naturally full of nutrients, which cause growth in plants. The ozone layer protects the earth from harmful rays from the sun. Natural resources are the most effective source of energy, from oil to power produced from a raging river.
Husband and wife join together and from the two comes a precious human life. The mother is naturally prepared to nurture her child.
There is a trend here. Humans are not the sole source of life and do not sustain life. Everything is in perfect harmony, held together by a Source much higher than ourselves. Creator God, sustainer of the Universe, former of the galaxies, provider of life.
