big, friendly, invisible things, do not require anyone's proof. neither however, are they constrained by anyone's speculation as to the nature of their existence. there is nothing that requires a thing to need to exist in order to do so. if there were, we, would not either. proving or disproving, the existence or non-existence, of non-physical things, is self serving and pointless.
^ Those things can convince an individual for sure (i for can relate to that) but it is not proof to someone else at all. It is more of a feeling/awareness than some kind of evidence you can show to someone else that doesn't has that same feeling/association when they look at those things. There simply is no absolute proof (so far ), that's why it is called believing and faith I guess.
i look at these things. i see too much complexity and diversity to be the work of any one hand, no matter how powerful, intelligent, or wise. i have plenty of other personally anecdotal reasons, to feel non-physical things exist, but not that there is some single hierarchy of non-physical things, that everything outside of, is somehow wrong. i see nothing in nature, nor in my personal experience, to support the latter assumption at all.
