to predict, explain, or discover phenomena of interest.
Explain and (not or) predict*. There is no point in a model that only describes experimental data. We say, “With enough parameters, you can fit any data in any model”.
* Also, it has to predict something that can be measured. This is the reason why particle physicists do not consider string theories as something serious (more like a math exercise).
