>Some god must be real.
Give a proper definition for God with a set of established attributes. There's people claiming a bearded man in the sky is god and others saying nature is god. I want a set definition.
After that, it would be up to someone to find some documented evidence of that god. A picture or video and for that evidence to be independently verifiable.
Once every other possibility is eliminated, I would be willing to believe.
>We can know a specific god exist
Similar to above.
>Humans do have immortal souls
Demonstrate a function attributed to the brain that can work independent of the brain. Memories, feelings, etc.
Or successfully contact someone from the otherside under controlled conditions.
>People need religion to build a lasting and stable society.
Attempt at building a lasting and stable society absent of religion both in inception and throughout and see how long it lasts. If it fails utterly, then you'd be right.
