(quote from RealReality.org/Real_Faith_and_Reason_Vol_2_-_Scientia.pdf)

While Christian thinking is sometimes baseless, ungodly thinking is always baseless. Christian thinking is baseless when a Christian slips into godless thinking. We Christians aren’t always following the leading of the Holy Spirit. We ought to be, but we aren’t. Whatever the Holy Spirit didn’t initiate and say through us is godless.

There’s nothing wrong with asking a question to point out that an ungodly claim has no foundation in truth. Just don’t think your questions disprove the ungodly claims. You can use truth to disprove a false claim. Only truth can prove or disprove any claim. Truth only comes from Christ. Even though an ungodly thinker cannot possibly answer your question rationally, that doesn’t prove the ungodly thinker’s claim is false. It just proves the ungodly thinker can’t give a sound reason for making the claim. The unbeliever is making an unsupported claim or a claim supported by smokescreen fallacies.
