It always amazes me how angry a good percentage of scientists get any time something related to a god is mentioned. I mean plenty of scientists believed in gravitation waves before they were discovered, why is it so bad if other scientists believe in a creator.

Actually, final section of a paper is an acceptable place to put your own personal view on the issue, and it is quite common for people to do so. And, since there is nothing within science which contradicts the existence of a creator/intelligent designer, so what if the author views the existence of a creator?
