The fact of evolution is well established, starting with the age of the earth.
The issue is: can random mutation and natural selection account for the evolution of complex creatures? The great scientist JBS Haldane said, "I do not propose to argue the case for evolution, which I regard as being quite as well proven as most other historical facts, but to discuss its possible causes, which are certainly debatable."
One can say 'No' to the orthodox explanation of the causes of evolution, without then having to believe that the evolution of complex creatures was the project of some supernatural entity. It's okay to say, "We don't know yet."
There are things about the universe which are very strange. Even Special Relativity flies in the face of our common sense understanding, even though it is compatible with classical physics.
Then get to quantum theory ... whoa! And... what is consciousness? We don't have a clue.
So there may be fundamental aspects of physical reality -- related to complexity and inherent order -- that we lack the basic concepts, as yet, to comprehend. Lavoisier was a great scientist -- his execution by Leftists was a huge loss -- but the fact that no one in his day understood, say, electron shells or even electrons -- meant that his understanding of chemistry was necessarily limited.
Not to mention the possibility brought up nearly a century ago by the scientist quoted above, that the universe may not only be"queerer than we understand .... but queerer than we can understand."
