"Did you not mean that astronomy can make entities superfluous for the entirety of existence? Because then you just said a false thing. hth"
I don't see how. If I say that traffic lights work via little gnomes, and then you open one up and don't find any, you won't accept as valid a response that they just hide when you try to look for them, or that they're invisible in the first place, or that we're just incapable of sensing their presence for this reason or that.
"Really?"
Godless Morality, Peter Singer. Read it. Morals deriving from a divine source raise a particularly difficult question for many atheists and theists alike: are things like rape and murder wrong solely because some divine being said so? Why aren't they wrong because of their tangible and undeniable effects on people? The same divine being could just as well say that murder and rape are right, after all, and who would we mere mortals be to question that? If you're one of those theists who tries to fix this up by saying that god is good and could never order evil, or something of that sort, then there /already exists an objective morality sans divine right./

"(and actually function better without religion)"
You sure? The Reign of Terror?"
People on medical ethics committees are among the most conscientious people I've met, and they don't do their jobs by consulting the ten commandments or any other "divinely-inspired text." They look at the ramifications of medicine for human life.
"Plenty of assertions are unsupported by the material world. How COULD certain assertions be supported by the material world? "The material world is all that exists" couldn't be supported by the material world. So what now?"
All evidence seems to suggest that cognitive processes and all aspects of human perception depend on the brain and what are ultimately chemical reactions across the human body. We can't, therefore, perceive anything but the material world, and why should we posit anything but the material world exists?
"You're slipping from my existential quantification to universal quantification."
You misread me again. I made an ambiguous statement, you assume I meant to write the universal reading (if English habitually disambiguated such things), and it seems to me like your conscience betrays you.
""I wouldn't exactly call dismissing people out of hand 'engaging in discussion,' personally."
[citation needed]"
Personal experience my friend, I wasn't making a universal truth claim.
"I can at the minimum assign the predicate "divine" and "existent" to a divine being, right?"
Divine meaning "godlike," sure. Why existent, though? You'll need to support that one.
"Omnipresence is one of those predicates!"
It's certainly done a good job of escaping the notice of modern science which leads me to believe it doesn't exist. I'd furthermore ask how you got this predicate.
"If you fail to recognize a thing, it doesn't fail to exist, man."
What is there to recognize? It's also funny how you try to define religion into things like the golden rule.
