True.. belief that they are is a belief in "magic"..
Evolution(generally) is a belief in "magic"..
That feathers evolved from scales.. for insulation or flight purposes.. Evolution theory is like a scientific cartoon.. You just suppose(think up) that something happened and it "probably did".. they suppose..
People that believe nothing can believe in anything..
I admit, believing that God created creatures is simple..
But surely as rational as evolution is.. since literally NO ONE can ever know for sure.. What actually happened.. At least in this realm of understanding..
Evolution(generally) is a fairy tale for grown-ups..
It appears that "atoms" are NOT little balls revolving around some nucleus.. at all.. No one seems to know WHAT matter is.. or even energy.. exactly.. What life(and death) is, is totally up in the air..
All of the historical sciences - evolution theory, anthropology, archeology, Egyptology - deal with a very spotty historical record. Moreover, they fit individual finds into a blueprint theory which is in effect more of a paradigm than a theory as compared to physics, etc.
If complete remains of every creature that ever lived were available to the investigators, sequenced serially, then the underlying paradigm could be subjected to rigorous tests on a confidence par with physics.
As it is, belief is required. For some, belief in the paradigm. For some, belief in God - with of course, a wide range of understanding of both Scripture and the paradigm. Some one, some the other, some both.
