And still, with lack of information as to what happens during the afterlife or time of death, we still can't say who is right or wrong.

We are literally using the same terminology in different means. You're saying that people can be wrong about the afterlife, and that is absolutely true. What I am saying is that no one can be proved wrong. Until, well, they die.

So in our conscious reality, despite how people see reality, etc, no one can be logically incorrect about a topic that has no information to further proof. Someone cannot prove to me that there is a heaven and I, in the same light, cannot prove that there isn't. So neither, in the living conscious state, are incorrect. Once someone dies, than they find out, or they don't. Which is not the living conscious state.

So right now, typing this, no, no one is wrong believing conclusions that come from their own individual state and sets of belief.
