Why is it not useful to view science as a set of facts?

If science is to be defined at, science is a systematized body of knowledge. Science is where the organized set of facts were obtained and is used as a tool, model or paradigm to gather such evidential data. Science is not a fact but an existential body in which comprises the study of the anatomy and physiology of a certain object by the means of observation, hypothesis, experimentation, interpretation and conclusion of the gathered facts. Or what others would describe the scientific process.
