Such explanations fail to explain the vast mechanisms and systems of function, let alone origins!  Such simplistic claims offer nothing more than a rudimentary arm chair explanation which describes beliefs, worldviews, but certainly not science.As an example to clarify:  A coroner removes a heart from a cadaver during a medical class and asks the class what organ is this?  The class answers unanimously: the heart.  There is no classroom dissension or argument: it is the human heart.  However, “heart” is merely a name used to categorize and explain what object we are talking about.  However, beyond this, it does not provide any explanation to the mechanism of biological function of the heart, let alone the origins of such a biological machine.
