I would ask, no demand, evolution to answer the crucial questions to their argument: how microorganisms evolve into people, how lifeless matter became life and where that matter came from in the first place. Taking their argument at face value because they don’t want to deal in metaphysics is bogus. If they can’t prove intelligent design is false, then it remains a possibility, and, if intellugent design is true, then its basis is no longer in theology alone.
Why just evolutionary biology? Why not demand that every discipline either explain where any matter or energy they deal with came from, or stop teaching?
“If they cant prove intelligent design is false, then it remains a possibility,...”
Evolution IS intelligent design!
