Hi everybody. This is stolen from an article I read sometime ago, no clue what the name is.
When you come across a pile of rocks, and pick one of them up, you can quickly see how complex it is. The probability of that rock having formed in that exact shape is astronomically small. It'll be such a complex shape, and would take so many parameters to fully describe it.
On the other hand, you could come across a perfect cube in the rock pile, and infer that it is designed - because it's so simple. You could just use one parameter to describe it (length or width or depth). Doesn't simplicity infer design rather than complexity?
