But remember that the evidence you see is often a product of your viewpoint in the first place. People who watch/read right-wing media sources get an entirely different set of facts than people who watch/read left-wing media sources. Both are biased one way or the other.

If you live in a society that is mostly religious then you will encounter proof of god's existence every day. If you live in a society that is mostly atheist, you will never encounter any proof of god's existence, and you'll wonder how anyone believes that crap. Which is the belief based on truth?
