I think there is a major difference, in comparing 'God', to imaginary things.
There is little to no difference. Fiction is fiction, and I would argue that all any theist has ever done is attribute/imagine all the things to it that they want "god" to encompass and/or slightly plagiarize/borrow other people's ideas of god/deity and
then add their own spin. This idea is supported by the evidence - in the form of hundreds of sects of Christianity, believers with hundreds of ideas and different interpretations of scripture - believers nearly at one another's throats over ideas for which they have no evidence other than The Bible, and, of course, the fact that there are so many other religions and ideas to begin with. Some of which have come and gone from this world entirely. People believed in them, and now there is no one left to. Certainly doesn't mean it was "true" while the people believed it. I think even YOU would agree with that.
1. There are millennia of human testimony, to the existence of God. Nobody seriously believes in the tooth fairy.
And humans have been wrong for (relatively) huge lengths of time about many grand facts surrounding the nature of our planet and the universe. The idea of "Flat Earth" prevailed for quite a long time. People thought the stars were holes poked in some kind of dome for quite a long time. People thought sickness was some kind of mystical tainting of the blood for quite a long time. People can be wrong... even about serious things. And many of those things have a lot in common with the prevailing ideas of God in that no one scientifically tested or examined, or no one was
able (sometimes only until instrumentation and widespread use of such technology was available). And then we dispelled those ideas as nonsense. We may never be able to do that with "God" specifically, because the idea itself is unfalsifiable without some further ability to investigate or demonstrate proper aspects of God - which no one ever seems to be able to offer.
2. Humans have a 'sense' of 'something'.. angst, purpose, eternity, that belies claims of nothingness.
So what? Most humans also have a sense that something might jump out of the darkness at them after watching a scary movie. That doesn't mean there is something that can materialize out of darkness, does it?
3. Ignorance or denial of a spiritual/supernatural realm does not make it go away.
This is such a horrid point... this doesn't even work in your favor. The "spiritual/supernatural" was never HERE to begin with. It can't be demonstrated, can't be produced/reproduced, can't be measured, can't be examined. Minus those things, it is as good as non-existent. It is folly to say that there is, definitively, a "spiritual/supernatural realm." You cannot, in any way, bring forward verifiable evidence of this. You cannot.
4. This 'sense', or awareness of the supernatural crosses all time, region, race, and culture.
So does being afraid of the dark. Who cares? To my mind, this is evidence that the human ego is extremely strong and works on most people's minds unchecked most of the time. So many people I have encountered feel they are just about OWED a "purpose" to their lives. That they are entitled to some kind of "meaning" - that they are "destined" for more. That is plain and simple conceit, arrogance, hubris - and it means nothing. Your mind is no more important a part of you than any other. It seems that way - TO THE MIND, but minus the heart - you're dead. Minus your digestional tract - you're dead. Minus your skin - you're dead. Minus your lungs - you're dead. Through artificial/medical means, we can overcome certain deficits - but the same can be said for the mind. We can keep the body alive through artificial means even without the mind active at all in the body. The mind is one part of a whole, and is no more, or less important than those other parts. But it THINKS it is... and that's where I believe all this "supernatural"/"god"/"I hope there is more out there for ME" crap comes from. All of it.
5. Atheism has always been a small, minority view, and has grown recently mostly from institutional Indoctrination, and zealous proselytizing.
It's not "proselytizing" in the slightest. It's getting people to realize better ways of thinking lead to rejection of claims until they have been demonstrated to be correct/true. That's it. Atheism just follows naturally from shifting to those realistic ways of thinking. Letting go of your interpretation of the world that puts all sorts of fictitious levels and layers on top of it. Unless you can demonstrate it, IT MAY AS WELL NOT EXIST. This is true of anything.
6. The human mind/soul/essence is not satisfied with a godless, naturalistic explanation of our existence, but innately senses a spiritual reality.. in general.
You can't equate "mind" and "soul' - you can't. There is precisely ZERO evidence of a mind without a body moving on into "eternity," let alone even a couple seconds. And there is a fat, whopping TON of evidence that suggests that the mind is so intrinsically tied to the body (and therefore to the materials of the body) that when that body is damaged too severely, the "mind" goes bye-bye. And if the "soul" is something different than the "mind" when the "mind" can be damaged by physical hurt, then I don't given one flying crap what the "soul" is, because it isn't what I consider "me" - it isn't my consciousness and memories if those can be lost but the "soul" somehow remains. And if it isn't my consciousness and memories, and it never once presents itself to me in reality - then I DON'T CARE ABOUT IT.
7. Minority, crackpot, and outlier opinions have always come and gone, in man's quest for Truth about our existence.
Yeah - and your crack-pot opinions have come, and they are on their way out. Don't let the proverbial door hit you.
8. Emoji can go either way, and, like science, do not sanction atheistic naturalism.
I honestly believe sometimes that some people think emojis strengthen the look/feel of their argument. It is a sad, sad state of affairs. Shows a complete lack of fundamental understanding of what makes communication worthwhile. To hell with emojis.
