“If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.”
Darwin

In reality that is true. A dozen irreducibly complex systems operate within our bodies, systems that stand no chance of having been created by naturalistic evolution. But those who are philosophically committed to a material universe arising from nothing by nothing, those who are philosophically committed to life emerging unaided from non life, Darwin’s true statement is simply ignored as they press on with their absurd, incoherent faith system.
