I don't really find much value in anything metaphysical or spiritual. Growing up surrounded by it as well as religion it has become incredibly apparent that it is all made up. I understand the desire to imagine there is something more to us than matter being funny, but everything we know suggests we are only matter.

I think we have free will and intelligence as an emergent quality of the biochemical processes that we are formed by, conciousness may indeed be more than the sum of its parts. Perhaps conciousness is the result of the quantum superposition of what happens in our brain, but I do not think it is reasonable to entertain the concept of some unmaterial soul, some entity that exists beyond the body and brain. All of our best evidence tells us the only logical conclusion is that there is no afterlife, or karma, or reincarnation. It really is not logical to believe in anything else when we can be pretty certain we already know nothing happens.

People still believe in other things, of course, or they at least entertain some ideas related to spiritualism. That is ok, belief is natural. I personally feel like truth is more important, and I am simply not convinced by "no one can truly know". Just because something can not be proven false does not mean it is possible. I know there is no afterlife and consider that a fact, because that is the only possible option.
