i agree to some extent. the nuance i would bring is that it's all based on assumptions upon assumptions. A lot of these assumptions are supported by proof that make sense (or at least seem to make sense). but even this evidence is often based on assumptions. But it has to be this way because a hundred lifetimes (let alone one) is not enough time to test every single scientific "fact" known to man. and even if you could test one, and the fact is proven, you'd have to run the test to infinity to prove it's right all of the time.
so yes, in theory, all of it is based on "faith" in what people before us discovered. but at the same time, when you start your car, you have "faith" that the rolling bomb you're about to start was designed properly. You have faith in the knowledge that the architects that designed your house used so realistically, you probably don't live in fear that your house will collapse on you while you sleep, etc, etc.
