The conversion experience prooves that humans are capable of emotional upheavals, it says nothing about the existence of god.
It might. It would certainly explain why they are having that particular emotional upheaval. I suppose it could be that emotional upheavals kind of happen spontaneously though.
We see an effect - the conversion experience. It's natural to ask about the cause. Those who have experienced it say that God (or some variation) is the cause. This is a common enough opinion. Why would we argue with them about it?
Perhaps we argue about it because we don't like the implications?
