The article “Where Did the Idea of “Millions of Years” Come From?” (https://answersingenesis.org/theory-of-evolution/millions-of-years/where-did-the-idea-of-millions-of-years-come-from/) by Dr. Larry Mortenson, traces the history of the deep time concept that arose in the field of geology in the late 18th century. It describes how this quickly took hold in academia and then the Church in the 19th century, eventuating in the great apostasy of the Church into liberal theology and the demise of biblical faith. That this has had a significant and devastating impact on societies and civilization as a whole cannot be overstated. Recovery can only happen by a return to orthodox biblical truth in perhaps another Great Awakening and Reformation movement by the Church.
