Actually I think we have evidence there isn't any existence after death. Many religions claims various different things. Does everyone just get their own wish fulfillment? Probably not.

There are various random claims of proof of something happening after death, contradictory and with no real evidence. When there's no evidence, and people make very contradictory claims while claiming absolute evidence but having now, .... it's probable that there's nothing happening. I'd like to imagine my deceased loved ones are still around somewhere, but I don't think they are.
