Please explain how you know that there is absolutely, definitely, no god of any description.
That's not a necessary question since there is no evidence to begin with that even remotely suggests I should ask that question.
The question I think is appropriate is, what best explains god beliefs? We have lots of evidence god beliefs exist among people.
I don't dismiss the principle in the scientific process that "proof" is not the goal. I could have been certain in the 1800s, if I were alive then, that the Earth's crust was solid. It might have cracks but I would have still been certain the crust was solid.
As recently as a few decades ago, I was certain bacteria did not thrive in the extremely acidic gastric juices, let alone be the cause of ulcers.
It is a standard part of the scientific process to operate with a presumption of 99.99999999...[to infinity]% certainty for some things for which there is enough evidence to have confidence in that level of certainty. But even the conclusion, I need O
2 to survive, which has one of the highest degrees of certainty you can achieve, is subject to the same uncertainty as the god question you disagree I could be certain about.
Is it certain you need O
2 to survive? You could test it over and over and always get the same result. But in science, you would still never achieve 100% certainty. It is obvious to us we need O
2 to survive, so we never think about the issue of 100% certainty when discussing that conclusion. But it was just as obvious to most people in the 1800s that the Earth's crust was solid and just as obvious to most physicians in the 1970s that bacteria were not the cause of gastric ulcers.
I prefer not to confuse the two issues, the matter of how one treats certainty within the scientific process, and the certainty of the evidence that gods are fictional human inventions.
I am just as certain there are no real gods as I am certain I need O2 to survive. The evidence gods are fictional creations is that overwhelming IMO.
The problem I have with your approach, "you can't know for sure", is that this is applied with a double standard to god beliefs. We don't apply it to the theory of evolution or gravity. We especially don't apply it the the conclusion we need O
2 to survive. We don't really apply it to invisible pink unicorns or invisible garage dragons even though many scientists pay lip service to the uncertainty invisible dragons and unicorns
could exist.
