I prefer to use that term for the Creator. There's a trucking company that uses the initials GOD for Guaranteed Overnight Delivery that I think is most disrespectful. BTW, I don't post at FR to get involved in Biblical discourses. I know some here enjoy science.
The bible uses the word God as His title, though not His name, without the little * therefore it is quite OK for you to do the same. To raise your level of piety above the bible is not a good thing.
I enjoy science and the bible.
