It is a choice to have a disbelief rather than a belief. But to say you don't have a belief is false.
Your conclusions about the world around you are then seen through the prism of what you have chosen to believe, and therefore will read and listen to those that also see through the chosen prism of belief, even though many different beliefs are looking at the same things.
To then claim truth in disbelief through the process of occam's razor with merely the same things that everyone is also observing is a falsehood, as the assumptions made rely on a foundation of lessons taught in the unprovable, unseeable beliefs in the same way other beliefs operate.
If we all have the same evidence of that which we can see, but no proof of how it came to be, our conclusions are then simply based on what we chose to believe before the evidence was presented. A faith in which our conclusion about what is unknown is correct.
To choose to disbelieve about a belief is still a chosen belief in disbelieving.
He’s given his proof to me and my family time and time again and usually it’s my knowledge of science and math that strengthens what I’ve seen. I’ve heard similar stories and proofs from countless Christians and nonchristians alike. I find it funny that because we can work out how God might have done something that makes it invalid of it being him. He created this world and time and time again uses his creation to show himself and do miracles in the Bible. He gifted us the ability to learn and encouraged us to explore and interact with this creation he gave us, even giving us a nudge when we’ve stalled in that progress. Science is not the enemy of religion, even if some people on both sides like to see it as that.
