Without a rigorous effort, the default claim is less strong and has not stood up to scrutiny.
no. the default claim is true unless proven otherwise, that is why it is default. it does not have to stand to any scrutiny. it is the claim that there is an invisible man in the sky, who is allmighty, sociopathic, sadistic asshole, has been torturing people since he created the world and in spite of being allmighty needs you to go to church every sunday and bring him money, that needs to stand up to scrutiny.
