And why would he do that?

E.O. Wilson in Consilience: The Unity of Knowledge

Perhaps God did create all organisms, including human beings, in finished form, in one stroke, and maybe it all happened several thousand years ago.  But if that is true, He also salted the earth with false evidence in such endless and exquisite detail, and so thoroughly from pole to pole, as to make us conclude first that life evolved, and second that the process took billions of years.  Surely Scripture tells us He would not do that.  The Prime Mover of the Old and New Testaments is variously loving, magisterial, denying, thunderously angry, and mysterious, but never tricky.
