100% positive there is no God?
Well, no - but, I'm not 100% positive about anything.
I'm fairly certain that all the "deity" and "creation" myths are just really myths - as most of them are simply absurd and have no supporting evidence.
As to "proof" - ultimately, one can only "prove" mathematics and gain evidence for the existence of something. You can't "prove" something doesn't exist, you can only gain evidence for it's contrary.
I agree that they are agnostic rather than atheist, but I think "coward" is an unnecessary and inappropriate smear in most cases. I don't think most Ivory Soap Atheists (99 44/100 pure) hold back out of fear, but out of a contrived notion of fairness.
Many were reared as theists and recall how certain they were that there was a God and yet appear to have been mistaken. That provides an understandable grain of salt and they fail to discern the difference between being programmed as a child to accept something on faith and falsely but sincerely calling it knowledge, and using logic, that is a system of thought based on non-contradictory data, and arriving at conclusions based on such.
They are further held back by such homespun bits like "you can't prove a negative," which many take as a rule of logic even though it is clearly a fallacy.
Then they tie themselves with the notion that certainty is a magic spell that will prevent them from having later epiphanies should contrary evidence present itself.
I suppose that they imagine some scenario where those of us who are certain are wandering through the rapture with our eyes closed unable to see the risen Christ as he gathers his elect or some such. They pretend that being certain is a vice and never a virtue. They are told that they must be open-minded in order to be scientific, that they must allow the possibility that any random assertion by any nut on the street might be true. Of course, science does not make such a demand anymore than medicine demands that doctors follow the Hippocratic Oath in order to heal. It is a contrivance sold to those who do not think for themselves.
It does not logically follow that being approachable by those claiming new evidence for old assertions demands that one never have been certain.
Sorry, atheism isn't strong agnosticism - it's just English words - and It's not "believer, agnostic, atheist" as in "big, bigger, biggest".
Atheism is a statement about belief - like I believe in god or I don't
Agnostism is a statement about knowledge - like I know or don't know the house key is in my pocket.
Have you ever heard the expression "Scientists have proof without certainty. Creationists have certainty without proof."?
Are you really absolutely 100% certain in anything?
You're playing with word definitions in what looks like an aggressive way to push people in to something -> "agree with me or I'll imply you're a coward ... you, you, you ... agnostic!!"
Mate, the type of "keybord bullying" doesn't work with me - I already had this type of conversation 15 years ago when internet atheism was new.
"You can't 'prove' something doesn't exist..." Why do people keep saying that when it clearly isn't so?
They keep saying it because it IS so.
Prove to me there's no pink elephants. By providing proof.
I personally don't "cling" to atheism - it's simply a conclusion I've come to, based in part on evidence of purely natural processes to explain virtually everything in my observations, and in part on the lack of evidence of a deity or magic or spirits .
Honestly, like any scientist (or honest person for that matter), if sufficient evidence came forward for the existence of spirits or gods or magic (or even mundane things, for that matter) and it was validated by various reputable people using the scientific method - I'd believe it - in much the same way I believe in cars and aircraft and gravity, etc.
I personally doubt that such evidence will ever become available.
"As to your challenge, why would I attempt to prove there are no pink elephants?"
By not addressing my point you've shown you can't do it or you have simply not found someone on the internet who can ...
... and that's because this IS the point. There is no way to do this.
As to "Why would you assume I disbelieve in pink elephants?" , but you're an atheist? Right? Have I go that wrong?
You don’t believe in God, do you? But you can’t say you don’t believe in Pink Elephants?
"Willa, please name a single professional logician who believes that you cannot prove a negative."
Sorry, here's two:
Here's one -> Bertrand Russell – and he did this explicitly in his celestial teapot argument.
Here’s another -> Peter William Atkins – said it when he spoke about Russell’s teapot.
You’ve heard of “Russell's teapot”, haven’t you Burden of proof argument? Teapot orbiting sun argument. Can’t prove it’s not there, etc.
Hopefully you're well enough read for that.
So ... er ... enjoy.
