> even now evolution is still only considered a theory No, you simply misunderstand what “theory” means in the scientific context. It’s a synonym for “explanatory model”. And “evolution” in this context stands for something close to “gradual change via random mutations and natural selection [as well as other, less important mechanisms]”. Calling it “theory” does not imply that it’s not based on observable facts, or that there’s doubt about it. It’s simply used to distinguish observable facts from an explanatory model. There is no “progression of certainty” from hypothesis → theory → fact. As another commenter has said, evolution is as much a theory as gravity.
