Not so fast.
Whether it 1. CAN'T; or 2. WON'T include the metaphysical is beside the point.
Science cannot include the metaphysical because the metaphysical will not fit into the scientific method.
The fact is that it does exclude the metaphysical. Not only that, but having done so, it presumes to tell us what is real.
Not at all. An atheist philosopher may tell us that the only reality is one that fits into the purview of science, but it is not science that tells us that or makes that claim.
Or we have a creationist like the recent poster JAL who, having bought into scientism, concludes that even God must be physical. Again, that is a philosophical conclusion, not one forced on us by science or laid claim to by science.
Now, I don't wish to make a moral judgment here, just a practical one. The effect is partial truth without even giving the benefit of the doubt.
This is where we get to philosophical differences about metaphysics. The materialist disavows the very existence of the metaphysical and so takes what can be investigated by science as the whole of reality. You and I would agree the materialist is mistaking a partial view of reality for the whole of reality. But note that science itself cannot tell you who is right.
A practical or even necessary barrier to being inclusive is still a barrier to truth.
Only if you hold that all truth must be found within the barrier. Why is it not possible, when science has exhausted its resources to look for truth beyond science? Nothing prevents the human mind/spirit/imagination from crossing the barrier. Only the mind dedicated to scientism would see the necessary discipline of science as impassable.
Maybe you MUST exclude metaphysics to do science. Fine. But, what is the effect on how this discipline sees in terms of the ultimate frame of reference?
The whole point is that the discipline does NOT see in terms of the ultimate frame of reference. One has to go to another frame of reference--the philosophical denial of metaphysics--to turn science into an ultimate frame of reference.
By being exclusive, this is the functional equivalent of an ultimate frame of reference. Of course for many atheists it is the acknowledged frame of reference. The latter is a separate issue.
By being exclusive, it stays within its discipline. You are really confusing the latter point with the first as if they were logically bound together. They are not.
What scientists would have to do is really be so very generous with the benefit of the doubt extended to miracles like six day creation, a literal Adam, paradise without death pre-fall, the flood, crossing the red see, the resurrection, pre-trib/pre-mil views of prophecy, a future corporeal paradise etc.,
Not qua scientists they don't. Not unless you can bring forward empirical evidence on these "events" which is subject to scientific evaluation within the scientific method.
In order to provide this "benefit of doubt" one must already leave the limits of science for a more ultimate frame of reference. A scientist may do this---since scientists are human beings as well as scientists and need not always act in the role of scientist, but not within the discipline of science.
Why on earth would there be any expectation that science say anything at all about views of prophecy or paradise?
Why do you even want to bring these matters to the attention of scientists if not to give a scientific cachet to your theology? And what does that say about your theology, except that you need to have it validated by science---so you are the one turning to science as your ultimate frame of reference.
and then we would really know whether or not it does claim to be the ultimate frame of reference. (Or the revelations to Joseph Smith and Mohammed for that matter.)
And the fact that science does not and cannot judge on these matters confirms that either a) it is not an ultimate frame of reference, or b) as materialists claim, it is an ultimate frame of reference and all of these "revelations" are equally unreal.
Note again that science itself cannot distinguish between a) and b).
Does the six days of creation get the benefit of the doubt from anyone?
Of course. It gets the "benefit of the doubt" if your ultimate frame of reference is open to the Omphalos hypothesis. As apparently yours is.
But that does not fall within a useful scientific paradigm and is also suspect theologically.
IMO there are simply better theological bases for understanding the six days of creation.
