You're right.  In science "prove" means that "I have a model which makes
verifiable predictions of the outcomes of experiments."

Conforming to observations is useful, but if you can't devise a new
experiment and then use the model to predict its outcome to within some
known tolerance, then it isn't a useful model.

And no models are perfect insofar as they predict the outcome of *all*
experiments no matter how extreme the conditions.  When one passes that
boundary, it is the job of science to devise a better model.

That said, given the most useful model we have of how the universe
behaves, the Sun is at its exact center, as is everything else.
