I suppose it depends on what type of 'god' we're talking about.
Don't let me define the term for you. I'd rather you do that, and explain what type of evidence you might accept. I'm not insisting on any particular qualities per se, although it would have to involve some type of intelligence beyond the human level.
But if it's the type of supernatural deity promoted by your mainstream world religions,
Woah. I'm not shoving any particular definition of the term down your throat. I'd rather not do that in fact.
then I'd need evidence on par with any other phenomenon.
How are you defining the term "evidence"? Is there "evidence" for non standard models of particle physics, or big bang theory in your opinion? Is your standard of evidence purely empirical, or something more along the lines of the way the term is used in astronomy today? Like the stars in distant galaxies, nobody really professes to "control" God, so any type of 'evidence' used in at least some branches of physics is not typically a purely empirical (lab demonstrable) standard of evidence.
Basically, there needs to be some sort of detectable measure that specifically applies to said deity that is readily repeatable, not contingent on pre-existing belief, and not otherwise explainable by more mundane phenomenon.
One such "experiment" was described by a Christian earlier in this thread. Have you tried that particular technique?
It basically comes down to extraordinary claims needing extraordinary evidence. Show me the extraordinary evidence.
I'm not defining God in this thread, I'd rather you do that. God can be extraordinary if you like, but I'm not emotionally attached to God being anything other than "natural" and consistent with the laws of physics.
No evidence. At least nothing that suggests the existence of a supernatural deity as per your mainstream, Western religions.
I'm not claiming to own anyone else's religion, other than my own, and I don't define God as a "supernatural" entity to begin with. You're welcome to reject any and all "supernatural" definitions of the term "God" as you see fit. It's no skin off my nose.
In general, I've found people's personal testimony to be a combination of cultural influence coupled with mundane phenomenon which they then ascribe to supernatural origins.
Not everyone ascribes such experiences to "supernatural" origins. I can appreciate the "natural beauty" of the planet and have a "spiritual" experience without evoking anything particularly "supernatural" in origin.
And that sometimes includes things I've experienced myself, but I have no reason to believe there is anything supernatural involved (particularly things related to sleep and dream related phenomena).
Like I said, I'm not emotionally attached your definition of the term God, I'd rather you do that yourself, and explain what type of evidence you might accept for whatever definition of that term you choose.
