This reminds me of the episode of South Park where Cartman travels into the future to play Nintendo only to find a post-religious world mired in faith-based fighting.
If your quest for understanding takes you down the path of science or of religion or both, at some point you are going to have to take something on faith, and to succeed you will eventually have to defend that faith - usually against someone else's faith in something else.
We all have our cross to bear.
