This is confusing nomenclature with practice. There is also no such thin as "Computer Science," or "Earth Science," or "Mathematical Science," or for that matter "Library Science" either.
That is just my point.
I think you are obsessing ove nomenclature. There are sciences that are mostly experimental in practice, and there are sciences that spend most of their efforts trying to reconstruct the past.
Your assertion that some kinds of science don't exist, or aren't REAL SCIENCE is just your personal opinion.
Labels are just labels. They aren't reality.
