I can't speak for OP, but for me it's because this place is full of engineers who place their faith in evidence-based reasoning.

I have an engineering background, and was even gifted The Knack.

I don't think the two are mutually exclusive.

For example, there is the idea of Theistic Evolution.

I definitely like evidence-based reasoning, but it doesn't answer everything.

Engineering (as distinct from something like math or science) is more about applying, rather than discovering, knowledge. Some folks just treat the models and equations as mantras handed down by some all-knowing being (the professor). The equation shall be recited in the homework, at length in the project, one final time in the exam, and then we shall release it to the universe and free our minds of it.

This kind of implies you believe there are no Christian (or any religion) engineers. Which is very clearly not true.
