Very interesting and balanced response.
I think we choose to believe logic(maths,physics) based on some form of faith, it's more scientific and based on peer reviews but ultimately there are times when some of this logic starts to break down e.g when you start looking at quantum and all the interesting things that can happen in theoretical physics with multiverse theory.
As far fetched as it can seem, I don't think we can totally count out some form of mysticism or higher power. What I would say is that the current versions we have been given are all man made so by nature they have all been manipulated in some way e.g crusades or more currently, the conflict in the middle east.
Some people are afraid of the answer being as simple as "we don't actually know" so they find the closest thing they can stick with to give them purpose.
Option 3, agree with others, there are other privacy focused instances.
