It was all just another priceless accident. It maintains a level of sugar in the human blood sufficient for energy, but, without it, all of us would fall into a coma and die. No one created it. The sun stokes a fire just warm enough to sustain us on earth, but not hot enough to fry us, or cold enough to kill us. For countless centuries in countless places the forests and the vegetation perpetuated themselves without man's help.
Clouds bring rain and shade.
A very lovely accident. A salmon will swim upstream to have its babies and die and it will jump up fish ladders to do it. Illnesses have specific symptoms. It's all accidental. This reminds of the evening a minister went for a walk down the beach with an acquaintance, a rather well- known atheist.
