> a religious or spiritualist meaning to it, which is far from the truth. It's a question that arises from scientific curiosity that we hope to answer one day.
a) it is wrong to say definitively that it is untrue. there is no acid test for the existence of God nor of spirit.
b) religious and spiritual traditions have wrangled with this very question for at least 3000 years. it is not a 'scientific curiosity'. It is one of the most fundamental questions of human experience.
a) there's an infinite amount of things that can't be proven/disproven and this includes all sorts of human imagination. We should focus on things that we can actually prove or disprove. The source of a god is human imagination, so you can't even prove that any god exists because you just don't know what it is (iow what exactly you're trying to prove).
b) This being a fundamental question proves scientific curiosity. We wouldn't have achieved current technology if not for scientific curiosity.
