No, you are asked to accept the evidence that you have taken the time to research and compare to your detailed understanding of science and engineering with which you have educated yourself.
Oh, wait...
That's exactly the ticket. Tarkus has more projection going on than the local megaplex. Sure, it takes years of study and experience to understand how Apollo worked at th detailed level. Some acquire it professionally and apply it not necessarily to Apollo-like endeavors. Others acquire it informally as hobbyists. But it can be done. And once done, NASA's books are as wide open as any project's books can practically be. Specimen spacecraft are available for inspection in museums. Cast-off specimens are available for purchase. NASA and its contractors present us with a detailed "How we did it" scenario.
Now if you don't have the time, talents, or energy to undertake a suitable study, then yes you are left to rely on faith. But left there essentially by choice. Corporate accounting doesn't interest me, so I've chosen to let others, who have the required skill, to do it on my behalf. And that entails faith and trust. I could, if I wish, acquire the skills and evaluate their work on my own. It's not as if NASA
requires us to trust them. It's simply the path most choose.
Conversely Tarkus has evidently chosen not to acquire any of the appropriate knowledge and skill. But instead he's chosen to put his faith in Eric Hufschmid (and likely others) to give him the digest version of what's "scientifically" wrong with Apollo. Rather than check it for himself, he's simply let others do his thinking for him. Time and again we find the conspiracy theorists are the ones with the deepest ingrained faith.
