I don't care what the Bible says about seraphims. The Bible has nothing to do with what I think about evolution. What I have seen about evolution is that scientists, like creationists, have their own belief systems, one tenet of which is called evolution. Evolution is apparently based upon observing similarities in animals at different points in the fossil records and assuming that they are related or that one is "descended" from another because they share common characteristics or appearance. This is not proof of anything. In fact, it is as considerable an exercise in imagination as that of the creation of seraphim.
I don't know what the truth is. But I don't assume anything when it comes to the things of this earth.
Common morphology, shared diagnostic features, similar range and ecology, and the changes fit a chronological sequence. Your dismissal of the evidence for common descent is nothing more than a strawman.
