Answer 1

You don’t have to know how wheat grows to use flour and make bread… people follow processes that work without needing to know *how* it works at all.

Look at driving a car; the average person has little idea how an engine functions, and often not even if their own car is front- or rear-wheel drive. It just magically goes when you step on that pedal thingy.
