Well, I don't see how 'God's sunna do not change' would rule out evolution. If anything, evolution of life follows the same rules all the time natural selection of variation among individuals over time.
If "God's sunna does not change", how does that become evolution, in accordance to religious and to some extent scientific beliefs. I am not at all comfortable with God in the picture, simply because I do not know who or what this cosmological God is to begin with, but I do know who or what gods and Gods were in ancient times. Evolution (i.e. changing form) is the direct result of Nature and has nothing to do with GOD. Natural selection, by its own definition, defines a specific limitation; meaning that only certain things are selected to make a natural change and not everything changes form, right?
Also, I view evolution as one 'theory of creation'.
I believe to some extent yes, but there's a fine line that seperates the two. Do you believe that only living and moving things evolve? How about stationary or solid immovable stuffs or "non-living" things?
And by the way, do you believe the Quran (an alleged words of a cosmological fathomless GOD) promotes evolutionism, creationism or both?
Though I am not 100% certain, I believe the fossil theory is a bit exaggerated and can be misleading; what do you think?
