&gt; <i>Science, in part, requires faith.</i><p>Only at the bleeding edge, which you don&#x27;t need to use in your everyday life. Most science-related things at human scale can be done with your own two hands; you don&#x27;t require billion-dollar tools to fiddle with materials science, for example. Youtube is filled with videos of people doing human-scale science.<p>The whole &#x27;science requires faith&#x27; argument is largely thrown out to give credence to religion. The problem with that argument is that the fundamental building blocks of science <i>do not require faith</i>, and you build from those. The SI units are convention - you can make your own. What constitutes validity is convention - you can decide your own way. You don&#x27;t <i>require</i> faith to start doing basic science.<p>On the other hand, religion&#x27;s  basic building blocks <i>require</i> faith from the outset. Person X is divine, &#x27;trust us&#x27;. God Y likes or doesn&#x27;t like that, &#x27;trust us&#x27;. And from these basic religious building blocks, whole edifices are built. For example, most catholics are unaware of how the bible was pieced together by committee. That information doesn&#x27;t affect their day-to-day lives, however the religious rules that do affect them are based on those fundamental building blocks that are unverifiable by anyone. Faith is required because the foundational blocks are not verifiable <i>at all</i>.<p>This does not happen in science - you can verify the foundational rules yourself, and build as far along the tree as your interest and tooling allow. Theoretical physics existing in the &#x27;faith&#x27; world is largely a canard - most science is not like this, and theoretical physics is at the exploratory edge of science, not at the core foundational blocks. In short, the Planck Length is defined by the meter which we can see and confirm; the meter is not defined by the Planck Length which we theorise about.<p>Not to mention that in general, &#x27;scientific facts&#x27; are constantly tested, and &#x27;religious facts&#x27; are not. The engineering capabilities of steel are in constant use in almost every part of our lives; if science was wrong about them, the material would fail in unexpected ways. The divinity of the christ figure... well, it isn&#x27;t even testable. Christ is only divine to christians, but a steel bridge needs to hold up regardless of the mental state of the humans using it.
