This seems to be correlated with a lack of exposure to reality in the professional work, as alluded to in the article.

The sciences that are not mathematics involve the world as it is, with every effect having a cause and vice versa. Mathematics is a big language with a lot of testable and reproducible rules, but there is nothing anywhere in science that I am aware of that even approaches explaining why those rules are what they are-- they’re the immutable laws of reality right there for all to see and confirm, and they just “are”.

I think that because the human mind seems to abhor an unanswerable question, phenomena like this that are so far from being explained really lend themselves to the “it must be God” explanation.
