The part where they dig the bones out of the rock is science.
If you don't like their conjectures, guesses, and postulations, you are free to develop your own. But keep in mind that the late Devonian was just a little bit different from what we see around us now.
From where do we derive the word tetrapod? Why do most animals have the form of four limbs?
Why do we have no more than five fingers? Acanthostega was experimenting with eight!
How did animals, and by extension those curious bipeds with four limbs and minimally effective dentition, come to be the way they are?
Answering those questions, and having your answers come to be respected opinion ... that's actual science.
My point stands....
Conjectures, guesses and postulations are not science.
What worldview you start with determines what conjectures, guesses and postulations you come up with. The same is true in my worldview.
Science has to do with the observable present, not the unobservable past.
Evolution and Creation are both faith-based propositions. Creation Scientists look at the same evidence as Evolutionists and come to far different conclusions.
The origin of life can not be divorced from the theory of evolution.....it would be a theory without a beginning. As such, there are only two ways that life could have begun....a supernatural act of creation or on it’s own. Science, since Darwin, has eliminated the Supernatural before ever looking at the evidence. Having done that, what other conclusions could they come to?
