First off, science does not ever deal in facts. Ask any scientist. And that's the first time I think I've ever heard someone claim religion was biological. Thanks for the laugh.
Actually sciences (and I am talking about physical sciences or natural sciences, not social sciences) do deal in facts, by trying to explain the facts, though observations of the physical or natural phenomena.
The physical phenomena or natural phenomena are the facts.
This “explanation” are attempts to understand the phenomena in a model. This model is often referred to hypothesis or theory. The model should include explanations as to
- WHAT this phenomena is,
- HOW does this phenomena work, and find out
- WHAT applications it may have, and
- HOW would one implement these applications.
The model should also include predictions. The purposes of having predictive models are to let limits and scopes as to how you test the model (eg perform experiments or find evidence through fieldwork...or even both).
The explanatory model and predictive model, in the hypothesis or theory must be tested, using observations (eg discovering evidence or performing experiments), and data obtained from the observations.
The tests do not only verify solid models, the tests would also refute any incorrect or weak models.
So the theory or hypothesis is proposed explanations that explain the phenomena or explain the facts, and in the testing phase of Scientific Method, using observations of the phenomena (facts) to determine if the model (eg hypothesis) is probable or improbable.
So yes, science does deal with facts. Science try to explain the facts, and use the facts (evidence) to test the hypothesis.
