Nice poem.
Your post reminds me of the ongoing philosophical debate whether belief is voluntary The Ethics of Belief (Stanford Encyclopedia of Philosophy)
I guess you fall on the "no" side of this issue, sun rise?
That referenced section reminds me of determinism vs free will debates to some extent. I suspect there is no simple "A" or "B" answer but instead sometimes it's one and sometimes another and perhaps even a bit of both. I can only report my experience and note that I know others who have shared it.
In a way it's like people who have had an NDE. Their lives and beliefs tend to be profoundly affected by the experience They may say that they know there is life after death which for the sake of argument is a very strong belief. Someone studying NDEs might come to the conclusion that there's a decent chance of life after death based on all the experiential evidence
