To me its all common sense and backs up the evolution theory.
I think the problem is that human mind is limited, in a sense that we try to rationalise everything. The universe in its entire existence, as well as what the spirit world is, are way beyond our comprehension.
Thats where a belief comes in. What we can't explain or prove with science, we have to either believe in it, or reject it. Fill in the gaps the way it suits us, our individual situations.
What if the only purpose of human species is to never understand/know/comprehend how it all works? What if we are just to move forward, hungry for the truth, seek for explanations for afterlife, that we are never to find?
