Evidence and/or a demonstration that a god exists. What kind of evidence or demonstration I hear you ask. To be honest, that’s a difficult question to answer. It would have to be something as rigorous as a scientific demonstration or evidence. Something that can objectively and independently be verified. Something we would require for anything else to believe to be true, outside of religion. One or multiple testimonies won’t do it. An old book won’t do it. Claims of miracles won’t do it. The rearrangement of stars to show the sentence in the sky “God exists”? I’m not sure that would be sufficient, but at least we have something extraordinary to talk about.
This is an interesting point - what would be evidence of a god, by which I mean a sentient entity capable of creating our universe. What finding would tell us that a creature that made a universe before our eyes (if our eyes could see it from without) wasn't itself a naturalistic product of THIS universe, that is, arose from abiogenesis followed by evolution to a sufficiently advanced technological stage to now be able to do what the multiverse, for example, did for this universe? None.
The arranging of stars would be the kind of stunt we might expect from superhuman extraterrestrials capable of doing it.
some people confuse emotionalism for spiritual experience.
That's close to my point - many are confusing the spiritual experience with the presence of spirits. The feeling is familiar to us all, although it is often not recognized or called spiritual. It's a natural psychological response to some experiences that manifests as a thrilling sense of connection, and can occur while stargazing, hearing rapturous music, falling in love, laughing, gardening, or admiring the family pet. As I indicated, for me, the mistake is to begin to invoke and attach spirits and otherworldly entities and realms to the experience. When we have that deep belly laugh with somebody, and for a moment, there is just you and the other, connected by a common bond, feeling the thrill of existence, he is having the spiritual experience, but rarely calls it that. When feeling the same thrill gazing at the night sky, he often does, but this is the same feeling (see reference to Ptolemy below).
I'd like to elaborate on this a bit more. Spirituality has nothing to do with spirits and everything to do with a psychological response to life and the world in which one experiences a sense of connection to nature manifest as a warm feeling, a sense of awe and mystery, and often, a sense of gratitude. It is an inherently emotional situation. There are several examples from history of men mistaking this experience for spirits.
The ancient Greeks did this with the muses. They didn't have a concept for the mind being creative. Creative inspiration was not understood as a product of the mind, but rather, as a received message from a creative muse whispering silently into one's brain.
Likewise with dreams, who most understand to be products of their own minds, but others mistake as messages being delivered to them.
And likewise with internal moral conflicts, which are often depicted as a devil and an angel sitting on one's shoulder and arguing through one's ears.
This is the same, except that many have not discovered that their apprehensions that they call God or spirits are also endogenous psychological states and not perceptions of external reality.
Ptolemy expressed a similar sentiment describing his geocentric solar system, one star gazers are familiar with when they contemplate the vast distances separating us from the stars of the night sky yet understanding that we are made of their ashes, and one feels a sense of connection and a thrill. Here's how Ptolemy described the experience: "I know that I am mortal by nature, and ephemeral; but when I trace at my pleasure the windings to and fro of the heavenly bodies I no longer touch the earth with my feet: I stand in the presence of Zeus himself and take my fill of ambrosia."
These are all examples of people confusing thoughts originating in their own minds as evidence of some external agent communicating with them.
Do you have a rebuttal of this? I'm sure that you reject it, but can you make an evidenced argument that contradicts it? I don't think you can. I don't think anybody can. It might not be correct - there may be spirits yet - but can you show it to be wrong? If not, doesn't that mean that it might be correct? Is that something a theist can agree with - that he may be wrong?
The fact that their are so many denominations is due to mankind and their interpretations
That was my point. That's the human fingerprint, along with the holy books that all look like human beings wrote them and all contradict one another. Compare gods to chemical elements. With gods, we have tens of thousands of religions, but only one periodic table of the elements. If we had as many periodic tables as gods, what would that say about the science? It would say that it is as untethered to reality (not empirical or evidence-based) as the religions.
they have a lot in common, as they all have one original root .. God.
Or, what they have in common is the misinterpretation of spiritual intuitions as evidence of gods as described above. It's very easy to do, so easy that almost no culture has been able to avoid doing it. I wasn't either, for awhile.
