If you were walking through the woods on a large, uninhabited island and came upon a place where hundreds of apple trees were perfectly arranged in rows exactly 8 feet apart, what would you conclude?
1) That evolution on the island had progressed to the point that apple trees could plant themselves in rows and keep other species of trees out? Or . . .
2) That you had stumbled upon an orchard that must have been planted and maintained by an intelligent being (probably a human or group of humans)?
Would anybody choose answer number 1? Of course not. Answer 1 is illogical and irrational.
So if evolution can’t develop apple trees that can plant themselves in their own, well laid out and maintained orchard, why do rational people (sometimes called scientists) boldly proclaim that the entire ecosystem of earth was laid out and maintained by evolution?
