Their religion is the scientific method.
While this in no way negates your statement, Heisenberg once said "The first gulp from the glass of natural sciences will turn you into an atheist, but at the bottom of the glass God is waiting for you." I rather like that. Though I haven't finished my glass yet.
Engineers, particularly program managers, live in a more balanced world which includes practice as well as theory. Most of the engineers I have known are religious because almost every engineer understands that elegant designs never produce themselves. They understand all of the factors required for a system to come together and to work as designed and never believe in mere probabilities.
Therefore, I'm not impressed with my physicists out there. As I once told a Physics Major grad student who didn't like one of my answers to a college examination question, "when I graduate, I'll be an engineer and have a job - you'll still be grading papers..Sorry".
Don’t have any numbers and I’ve often heard similar discussions from others, but when I’ve pulled the thread I’ve found that it is all urban legend. My degree is in Physics and every Physics major I’ve met in the last 25 years except two were religious in one way or another.
What I’ve found in discussions is that from both a practical and theory standpoint the more we find out and the less we realize we know, it becomes either terrifying or awe inspiring both of which lead to an appreciation of God.

Occam's Razor does not appear to be in his intellectual repertoire.
