Do you believe ideas when you don't understand the evidence?
Sure, technically, because evidence comes in many forms.
Could i mathematically describe every quark? No. Do I trust the scientists, and that theu have it right? I do. And the evidence that causes me to trust (not "have faith", this is a bet, not a belief with any absokute certainty) them comes in many forms; for instance, the quantum mechanical machine i am using to talk to you right now.
Dude, just give it up. You are not going to put words in the right order and turn everything into faith. You are not, not ever, going to drag evodence based knowledge into the ignorant muck where your faith resides. Just accept that they are different concepts.
