I guess I'm just trying to understand the thread.
In my humble opinion I think you understand it. It is, ironically, very simple.
You asked for a definition of god and you got one.
I got a couple, but mostly what I got was bullshit ideology. That isn't at all unusual. For any subject, especially controversial, religious or political.
You'll likely get as many different definitions for the word as people you ask. Is there more to this thread?
Nope. That's it.
Presumably, you think that a definitive answer is necessary prior to any discussion of "existence of god", yes?
[Sigh] Hmmm. Well, I think it a good idea to at least come to some agreement on the various definitions. Let's say you and I were discussing gods, and you thought we were talking about Shiva or Eric Clapton, and I thought we were talking about Amaterasu or Satan. You see where that would be a problem? It isn't that we have to agree with the definition, it's that we have to agree on which example of the definition we are talking about. So, if I'm talking about Satan: satan is a Hebrew word that means adversary, resister. It's applied to righteous angels of God and to mortal humans. So, it can be supernatural, but it doesn't have to be. When the Hebrew word satan is accompanied by the definite article ha, i.e. ha satan, it refers to the spirit being (cherub) who is considered THE satan. Satan. Like the Arabic Allah. Al (the) lah (god). Likewise, the word devil means liar, deceiver, god means mighty. So, when one of the Hebrew words for god appears (el, elohim, etc.) it is applied to mortal men, angels, idols, pagan gods, etc. But when it appears with the definite article ha (THE god, i.e. God) it refers to Jehovah. The same with the word lord. Thus, the importance of definitional distinctions. That's why Paul said there are many gods and many lords but to us there is only one of each, and he said their belly (love of food) is their god.
To an atheist God just means magic sky daddy of the Bible and gods means metaphorical applications of that, like "He thinks he's God." That doesn't necessarily mean he thinks he's Jehovah it means he thinks he's all powerful. Okay, what does that mean? Omniscient, omnipotent, omnipresent, omnibenevolent aren't concepts applied to Jehovah. At least not in the exaggerated sense that usually is presented by theists and consequently atheists. To demonstrate this, humans are omnivorous. That doesn't mean they can eat the space time continuum or chemical and biological weapons of mass destruction.
But, as there are many different definitions of the word there will necessarily be many different discussions about the existence or non-existence thereof.
But, you see, that isn't entirely accurate. There are many different examples or applications but there is only one meaning. There has only ever been one meaning throughout history in every language known to man. But there have been countless examples. The atheist doesn't understand the distinction because the
Masoretes (scribes) removed the name of God for fear it would be abused by the people. That's the reason why atheists and many theists think that God is a name of a specific Biblical character or THE God concept. They think saying God damn it means taking the "Lord's" name in vain when what it actually means is God (any god) damn (curse; predict or forewarn of danger, harm) it (anything, contextually; whatever "it" is).
You claim to want a simple answer, but as others have pointed out it's not a simple situation and simplifying it too much will necessarily reduce the utility of the discussion to nil.
No, I do want a simple answer and a simple answer is that the word god means, i.e. a god is, anything or anyone attributed might and/or venerated. That's how I would define it. Every god, metaphoric, supernatural, mortal, imaginary, real, fictional, non-fictional, past, present, future, etc. etc. is a god. Just like man is a man doesn't define each and every man, or lord, king, uncle, aunt, goddess, etc.
It only appears complicated because you don't understand the basic, simple concept or meaning.
The discussion of each man individually would be complex in the same sense that the discussion of each god individually might be but it's a simple concept. Construct. Word. Whatever you want to call it or apply.
