The only kind of real but sort of half ass proof that I can think of off the top of my head would be NDEs but that is it. Also, do you believe that if it were confirmed that we as humans have souls that hell exists? How about if we knew for sure that there was going to be some sort of after life? I am just asking hypothetically, because I go through phases where I sometimes feel sure there is no such thing, but then other days I kind of worry about it again! One of the main reasons I worry is because I am kind of the reason why my dad became an atheist and I would feel scared if I outlive him wondering if he is suffering because of me.
