So besides the bible, faith/belief is a part of our nature. And how we choose to exercise that need is a very personal thing based on our perceptions,life experience and environment.
This doesn't make the beliefs true, nor is it evidence that they are true. Personal experience is not valid evidence of the supernatural, as it could merely be internally generated.
If, as you say, this tendency is innate, the fact that religion is widespread is not evidence for the truth of religion either.
Some other kind of evidence needs to be presented to be convincing to non-believers.
