Why is that the inevitable conclusion? Isn't it possible that God works through evolution? Surely God could set evolution in motion, couldn't he? He makes the rules, and the universe abides by them...
The two beliefs are not mutually exclusive - just because I don't believe that God is intimately involved in every single detail of my life, or the workings of the world, doesn't mean I don't believe in God at all, does it?
That's what my Mom use to say to me too.
