Where do the instructions come from? How does the first cell "know" to split into two cells? If the cell somehow splits, how does it "know" to share the information between the two cells? Where do the instructions for ever more complex life forms come from? It can't "do what it doesn't know?" You see, inadvertently, you have stumbled on the most basic problem of evolution - increasing specified complexity requires massive amounts of information-input to happen. The unanswerable question for scientists is "where do the instructions come from?" "Instructions" require "information." "Information" requires "intelligence." Citing crystals of sand as an example to the contrary is not sufficient. There is far too much specified complexity in the universe to attribute it to chance mutations. Thus the name "Darwin's Black Box."
