Proving is different from persuading; one focuses on fact and why/how it is, while the other is led by bias and emotion.
Proving doesn't necessarily lead to knowledge, most of the time "proving" something is how facts are utilized when coming to a conclusion.
Persuading can lead to belief, though the act of persuasion is mostly seen in commercials, or any act of selling-
We prove things, by utilizing known facts related to the problem/questions
There are strong notions that we believe strongly in and cannot prove, it can be called Bias. An example of this can be but is not limited to: "Guns should be taken away from gun owners because guns 'kill'."
