The burden of proof is always on the person making the claim. If they can’t prove their claim, their claim is simply dismissed. You never have to disprove an unproven claim. This is how all reality works. Religious people blatantly lie about reality, they are never to be trusted.

The key to religion is the last frame. If you don’t do what they say, and think how they say to think, then they get angry and resort to abuse, violence, murder, and finally - genocide.
