It’s the cool thing about science. You don’t know, but you come up with what you think is a pretty reasonable guess. Then you test for it and see if it fits. Then, you refine and try to reproduce your results. Prediction can be quite good, once you’ve really tested for it, and actually seeing it is irrelevant.
Goes for species, physics, economics, climate, sociology, etc.
