The arrogance lies in the claim of knowing the unknowable. I can’t know for sure how the universe formed. I can’t know for sure what happens when we die. I can’t know for sure that there is or is not a force guiding the world around me and the events that occur. But if you believe in a god (or any form of faith that has answers to these questions or questions like them) then you are saying “I don’t know, but I know who does”, or to simplify “I don’t know, but I know”.
On the other hand if you read a study, or a science article, that says it has found evidence of the big bang and you say “I read in an article that a research team has found evidence of the big bang.” well now you’re claiming that you know you read an article. That’s a claim that is easy to accept and contains no contradictions. It doesn’t take much convincing for me to say that I do think that you read an article. No arrogance, just a declaration of an action.
The nuance here is that there is a difference between reading a study about the big bang, and believing in the big bang. If you’re being completely scientifically honest, you know that there is a possibility it could all be wrong. It might be a slim possibility. But it is impossible for all of us to examine all of the evidence in all of science, so while it looks like belief, it is instead maintaining a perspective that the people who are studying it are doing their best, and so far their best is pointing in a direction. That’s all. No need to burn people at the stake, no need to write anything in stone. Just people looking for clues and reporting that the clues are all indicating a given conclusion. Or maybe the clues they’re finding are pointing all over the place. Or maybe they did the math and the math said that they needed nine spacial dimensions to make an idea work but if they had them, all the clues would point to a given conclusion. And then people living in reality said “how do we test something in nine spacial dimensions?” and all the shrugs eventually resulted in youtube videos that made me say “huh, that’s interesting, it looks like maybe nobody knows how that works”.
One last stupid question: Have you ever noticed how the faithful hate it, or at least express friction, when you bring up things that would bring their explanatory framework crumbling down? Meanwhile scientists are like “This poses fundamental questions about our theory of blabblegabble. I’m super excited, I might have some really serious questions to answer very soon, and we might need to really do some serious sciencing. Where’s my [insert stereotypical scientific tool here]?”
Religion is arrogant when they use that as an excuse to decimate the population of indigenous people, when to force people to give 10% of their earnings to an institution, when they try to infiltrate their belief into a secular system, when they judge you for not having their same belief system… and, as a personal anecdote, when even the teachers bully you in your religious school because you chose not to go to church with the classroom.
Believing in something with no evidence or statistical confidence is arrogant because your belief says that everyone else’s belief is wrong.
A more humble approach would be to just accept your ignorance. Specially when you try to push your belief into reality, like politics, like most religious people do.
