Just because people have experience that they ascribe as being "religious" doesn't mean it's god communicating with them.
It seems to me that the people who seek and contrive to have these experiences have them, and people who don't, don't.
It's a one-sided interpretation of "evidence" which is entirely in someone's head.
I think the reality is that people have emotional experiences (and they can be manufactured) but just because some interpret those through a religious lens doesn't make for any compelling evidence that there is proof of god.
Why doesn't god convince a sceptic for once? Why does he only manifest himself to "true believers"? The clue is in the "believers" part.
