I mean, to me it’s more intelligent to consider we have no idea what’s going to happen after we’re dead and think about possibilities to prepare ourselves just in case our consciousness does end up in some afterlife. I have strong suspicions we’re just dead and nothing happens, but I can’t be certain of that. Reading books and thinking about different afterlives might help if you end up in one. We don’t even barely understand our own universe, which we live in, so who knows what’s possible here?
