It is often stated that the primary question is whether people believe in God or not. But I suggest that the primary question is whether or not people believe only in the physical, material world.
I do not consider this to be a trivial suggestion, because the jump from nothing to God is often too big a jump for people to make. It is much more sensible to confront people with the simple choice of whether or not the material world is all there is.
In discussing my faith with a group of friends who were somewhat mystified by it, I realised that fundamentally they could not come to grips with anything other than this physical world.
I could see that, while they were not dismissive of my belief, they simply could not comprehend that there might be something more that this world.. And I sympathise with that. There are times when I sometimes wonder if I am not the one who is deluded.
If one believes there is nothing beyond the purely physical/material then the question of God (or anything spiritual for that matter) simply does not arise. And that is effectively the end of the conversation unless one is prepared to attempt to try to change that point of view.
If one believes that there is something beyond the physical world then various possibilities arise.
It is only by examining these possibilities that one can then raise the question of God.
The position of there being nothing other than the material world automatically infers atheism though the reverse is not necessarily true. It is logically possible to accept that there are forces at work beyond the material world that are not God(s) but merely blind, undiscriminating powers. As such they would be beyond being influenced in any way and, consequently, not within the normal understanding of a god.
It is only when one has considered these possibilities that one can logically move on to conclude whether or not there could be ‘a’ God or gods.
Thus the primary question is, perhaps, the nature of pre-evangelism.
