Hello Cypress,
Nothing definitive has been determined, so it is only natural for each person to form their own interpretation of what is known and what is not known. One factor affecting belief is peer pressure. If one is immersed in a group situation where all members of the group have aligned beliefs, that reinforces one's own belief. If no church organization is involved, and one is free to examine their own beliefs without group pressure to continue a particular belief, then it is increasingly likely that divergent beliefs might emerge.
For me, I see science gradually chipping away at the tenets of religion. I see various religions in disagreement with one another, making it really just a game of chance as to which one might be chosen to follow, if one has none to begin with. Those who do have a religion they were brought up with, only have it because their parents made the decision for them. And the parents of the parents before them, and so on.
That being the case, it really comes back again to simply a game of chance as to which family one is born into, and how the parents treat religion as they raise their children. Are the children forced to follow the parents religion? Or are they fully educated about the actual world and the many choices available, and allowed to make their own decisions.
I choose to disbelieve that which is not clearly shown to be the absolute case.
I am constantly fascinated by the newest discoveries of science.
In science I trust.
