I think it is worth pointing out that for the vast majority of people, there still a level of 'belief' required for the modern science, not unlike the religions of old. There are very few laypeople equipped to think critically about, let alone verify, most scientific theories. As a result, they have to take it on faith that the "priests" (in today's world, scientists) are correct.

And even scientists can really only be be deeply familiar with the experimental basis for a few narrow fields of study. For all the rest, they too have to take it on faith.
