Willowtree,
Evolution has absolutely nothing to do with the creation of life. Evolution explains what happens
after life has been formed. I repeat, evolution is not about the beginning of life. That being said I see no reason why you have to conclude that god and evolution aren't compatible.
Now if I understand you correctly you are saying that any part of science that doesn't start with the assumption that god is exists is biased and part of this "scientism". But, if that is true then pretty much all of science would be as you say "scientism".
Which god(s) should the scientist assume exists? Is it still science if the scientist believes in say Allah? Can something only be by your definition "true science" if those involved believe in the christian god?
If this is truly what you believe are you really willing to classify "creation science" as the only true unbiased science?
