The insurmountable difficulty is this.....
The fact is that God isn't the creator of naturalistic processes in this worldview...
"Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations "
...is in direct opposition to this theistic creationist worldview....
"Joh 1:3 All things came into being through Him, and apart from Him nothing came into being that has come into being.
"
Now, if one were to change the definition to this....
'Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection, and other directed mechanisms, of small, inherited variations'
....that would allow for non-atheistic creationist impetuses. Not that the theory would be correct, but it wouldn't be an inherently atheistic creationist viewpoint.
