They may not but many do.
I won't disagree that some may, but because of the places I've lived - such as Oxford, London and Cardiff - and some of the work I've been involved with - such as medical and sustainable development - the majority of the many mathematicians, biologists, physicists, chemists, engineers, etc. I know, who are also Christians, see no conflict between the two positions. On the other hand, the people I know who really push that conflict are the likes of you, who seem determined to believe that there has to be a conflict - perhaps in order to validate your owm personal positions.
Instead, science is just one element of God's creation and, as such, deals with certain areas of that creation.
Is that a scientific stance? (The answer you're after is "no").
Shaker, if one believes that God created the universe, as these folk I've referred to state that they do, science must - by definition - be 'one element' of that creative process. As such, its neither a scientific or religious stance.
