Why knocking is so important.

gravity came up as some sort of faith that Drich wishes to impose on us, right?

In the sense of accepting someone else's word on a subject, in this case regarding gravity. In that sense we take a lot of things on faith. It reminds me of that video where someone asks Richard Dawkins why he, in effect, has faith in science. "Because it works" is his matter-of-fact reply. More than just that, it works in a repeatable and reliable fashion. My 'faith in science' is rewarded every time I turn on an electronic device. Or get into my car and drive somewhere. Or board a plane and take a flight. Or check my watch. Or any number of things that we take advantage of every day without ever having to understand the underlying concepts.

Faith in religion, on the other hand, is nowhere near as repeatable or reliable. The results are varied, from nothing at all to miraculous healing of deadly diseases or being saved from near-impossible odds. Without the ability to independently verify any of those accounts, even religious people snipe at one another. One man's "miracle from the hand of god himself" is another man's "satan transformed into an angel of light to deceive." And since one has as much evidence for his claim as does the other, we are left with a version of faith that works as poorly or as well as you pretend that it does.

But it wouldn't make the lights come on when you flip that switch.
