There's usually low risk in trusting that a contractor is an expert in electrical wiring if they say so, and I usually trust plumbers or tradesmen to know their stuff and do their work. And how many times I've been wrong.
But my point is that most people don't go through this verification process, examining the credentials of scientists, taking a look at the evidencie, studies, papers, reasoning, etc. that backs up evolution. So it's not a rational belief. It's faith in other people, or a system.
If people did that, they would get to the conclusion that a lot of evidence points at the possibility of evolution being true. But by no means it's proven beyond doubt.
I don't know about your education or professional background, but from my side as a software engineer I very well understand that you can pile up evidence that will point you in a certain direction, and afterwards you might get that small 0.1% that will turn things completely around.
Regarding your questions about faith, I would not say that's how faith works. I have reasons behind what I have faith in. Right now I would not be able to switch my faith to something else just because.
Hebrews 11:1 - Now faith is confidence in what we hope for and assurance about what we do not see.
That something is not visible does not mean it doesn't make sense.
Could I be wrong? I guess I could, by definition, and I would be rejecting a scientific theory. Could you be wrong? What's the consequence of that?
