There’s a reason that arguments about religion often turn into completely meaningless battles of empty words. Such arguments in general are based on standard logic and follow the scientific method of drawing conclusions based on a set of axioms and trying to find inconsistencies.
The big problem of a scientist trying to argue with a strictly religious Christian, for example, on an equal footing is that their sets of axioms are different. Sure, they are same for the most of it – one could maybe even say that the scientific axioms are a subset of the Christian ones. That is because the first and foremost axiom of a strict Christian is the absoluteness of God.
