Not being snarky. I'm just not sure what you're getting at because you appear to have accidentally left out a word.

At any rate, he did have a somewhat nuanced take, though not particularly in the ways that people often think he did. His language about wonder and awe were more about communicating the innate value of science than about caving to the cultural imposition of standardized pictures of the supernatural. Right in that very quote, he said (and he often repeated) that the belief in a thinking, caring, anthropomorphic God is "naive."

Your quote comes from a letter replying to a child who asked if scientists pray. Obviously he wasn't gonna say to a child that she's wasting her time, being irrational, taking fairy tales seriously. But he came surprisingly close:

"Scientific research is based on the assumption that all events, including the actions of mankind, are determined by the laws of nature. Therefore, a research scientist will hardly be inclined to believe that events could be influenced by a prayer, that is, by a wish addressed to a supernatural Being."

It IS true that Einstein held great reverence and wonder for the (still mysterious) fact that the universe appears to operate under fixed, self-consistent, and impersonal rules. He also had great humility regarding the fact that there will never be such a thing as "complete" knowledge, even with regard to those aspects of the world for which new knowledge will always be available (the "natural" world). I share all of these feelings, as do all of the scientists I've ever worked with.

But while Einstein regarded these as "a kind of" religious feeling, we should note that they are QUITE different from what he called "the religiosity of someone more naive." Religion claims to answer questions that, by definition, cannot be answered. That is not wonder and it's definitely not humility. While Einstein himself danced around between a few different words in his time (varying with the context of the conversation more than anything), by the standards of American language in the 21st century, Einstein was an atheist.
