You express "knowledge" that there is no heaven or hell, and you express "knowledge" about what a creator would value.
I would submit that you have no such knowledge at all (you are merely speculating in a way that makes you feel comfortable), and that your position is based on faith just as much as a Christian's position.
Yes, there is knowledge that there is no heaven or hell because neither of which are empirically proven or observable. Heaven and hell are positive concepts, arguing that these do not exist because neither are observable or proven is not based on belief. Logical fallacy.
I do not express knowledge on what a creator would value, I speculate. I don't believe in a creator so any attributes I would ascribe to it could only be speculative, by definition.
The Zen understanding of reality is broadly "nothing exists beyond the present moment. Everything else is based on conceptual thought which only exists in our minds, and our attachment to ourselves and our desires is what creates the illusion of a soul and a fixed self". I wouldn't call that belief, I would call that an unremitting and factual assessment of reality through observation.....but, hey, God made the world in seven days around 4000 years ago....almost the same I suppose!
I am not a Buddhist but this way of thought is concerned with what "is" as opposed to "what should be, or what the book says it is". There really is a difference.
However, I do not believe this to be infallable. We could live in a simulation, or it could indeed be a Christian God.....if any Christians are willing to attest to the fact Jesus may not be the saviour, God may not be just and it's just a good guess...
