Obviously you can’t prove it one way or another. That’s the whole point. Are you new?
Nope, I’m old.
But I prefer not to base my life choices on things that are unprovable, and one of us has claims that are backed by at least some amount of evidence (the existence of missionaries, documentation of brainwashing techniques used by the particular church that OP belongs to, documentation of the financial motivations driving said church to continue brainwashing people, the sheer utter logical ridiculousness of the specific claims of that church), and the other does not. So I’ll continue taking the default, rational, skeptical position, until there is sufficient evidence to do otherwise.
