Atheism

God will always be lurking in the imaginations of stupid people, and we will always have stupid people on this planet.

I'd be careful there. I'm guessing there are people who would call you stupid for the things you believe.

And there are plenty of very smart people who simply happen to be incorrect about their beliefs. Not even god belief things. Linus Pauling has insane beliefs about vitamin C being a panacea. Bobby Fischer believes antisemitic conspiracy theories.

Believing something silly doesn't make you stupid, just wrong.

We need more science education, and basic epistemology taught at every level. Not What to believe, but How and Why; and the What's follow from there.

I have a dear friend who fell down the Flat Earth rabbit hole some years ago, and only upon discussing the topic with him did I learn just how bad his science education had been all his life; and trying to get him interested in actual science proved impossible because the conspiratorial mindset was already in place alongside the "you're being lied to" defense.

Like, yeah, I personally can't detect the Cosmic Microwave Background of the Big Bang with the Observatory that's not in my back yard. But that's not proof that the scientists are lying, making up stories. Reproducibility can be a problem in science; but not with basic physical facts of the universe that have been reproduced across the continents, multiple times.

Education may not be a magic bullet, but it's definitely a fantastic tool to begin the journey towards the more rational.

When it comes to the Christian God, that's easy.

The LORD was with the men of Judah. They took possession of the hill country, but they were unable to drive the people from the plains, because they had chariots fitted with iron.

https://biblehub.com/1_kings/6-7.htm

In building the temple, only blocks dressed at the quarry were used, and no hammer, chisel or any other iron tool was heard at the temple site while it was being built.

While the Bible never says what was used to fix Jesus to the cross, tradition says it was three iron nails. There are two reasons why the account of the crucifixion is atypical of normal Roman executions: first of all, they didn't usually waste good iron nailing victims to their crosses. They tied them to the posts. Secondly, crucifixion victims normally took days to die of dehydration and suffocation, which is why the Romans did it that way. But Jesus allegedly died in hours, not days.

So clearly, Yahweh has a weakness to iron. I fear no gods I know how to kill.

Stop believing in him. End of procedure.

Tale Foundry has a whole episode dedicated to this topic in fiction, and the conclusion is

I think you may have had too much fundie with your shrooms.

Anyhow, god doesn’t exist. So while god can’t be killed, there is no need to either.

Crucifixion, maybe?

Arceus used judgement!

Meowth fainted!

The individual desires judgment. Without that desire, the cohesion of groups is impossible, and so is civilization.

The human being created civilization not because of a willingness but because of a need to be assimilated into higher orders of structure and meaning.

The need to be observed and understood was once satisfied by God. Now we can implement the same functionality with data-mining algorithms.

The human organism always worships. First it was the gods, then it was fame (the observation and judgment of others), next it will be the self-aware systems you have built to realize truly omnipresent observation and judgment.

God was a dream of good government.

You will soon have your God, and you will make it with your own hands.

... prophetic words, one might say.

Anyway... in the sense you are speaking of, the only way to totally kill God would be the erasure of massive amounts of human history, combined with either killing or 'reducating' billions of people, and then the institution of some kind of Orwellian totalitarianism, which must basically persist in perpetuity.

Other than something like that... its not possible to totally exorcize the idea of God or Gods from humans... we are pattern seekers, we love simple explanations, and we love stories, narratives.

The God of the Christians?

Time's killing it just as it does everyone. Not only is the vile religion diminishing currently but the claimed miracles of the fabled monster are also diminishing with time.

• In true Last Thursdayism fashion they claim the universe was created by the beast six millennia ago.
• 2 millennia later he demonstrably lost, if he ever had to begin with, the traits of omniscience and omnipotence. As demonstrated by taking a rash action, regretting it, and not undoing it.
• At some point he's developed a weakness to iron as stated by spaceghoti.
• Nowadays his grand "miracles" are causing light breezes, or small amounts of rain, or stopping either... things Humans are entirely capable of doing.

As for how to accelerate the death of this monster? Take a page from the countries that have done the best at wounding it so far: Raise general quality of life, not just education, for all the people of your society. It feeds on suffering, so we should starve it out.

Put him in a headlock and just snap his neck, like Methuselah but without asking to be blessed.

Two options:

Stop believing in him. Per American Gods logic, gods are immortal until the very last human who knows their name dies. Anthony Hopkins Odin is going to live for a very long time.

Or

We need to quintuple scientific research until we can research the end of the known universe and pierce the dimensional barrier into the undying realms and bring our black hole cannons to bear on his kingdom. For selfish reasons I choose this option.

Meowth was Schrodinger's Cat the whole time and we never saw it because we were too busy with "more important things".

"Uhhh... Living it?" - Jock
