==History is not a science. You are mislabeling science. How would you repeat an experiment with Alexander the Great? It would be impossible. There is no such thing as “historical science”
When I say historical science, I am refering to the various branches of science that attempt to reconstruct the past. And since you mention Alexander the Great, one of the historical sciences that would be utilized to study the history of Alexander would be archeology.
The historical sciences also include historical linguistics, evolutionary biology, phylogenetics, geology, cosmology, etc, etc.
No, you are referring to the literal Biblical account of creation. Archeology will never reproduce Alexandar the Great. Nor is it concerned with him. That would be history books. The “historical” sciences you refer to explain in provable/disprovable/repeatable/testable ways how things operate/exist/etc now and through provable/disprovable/repeatable/testable ways how they operate/exist/etc in the past.
The words History is simply an account in words of a past happening. You are mixing the two words in a contradictory manner
