the judgment is not whether a god exists or does not, but whether their is any
good reason to believe in a god or disbelieve. The initial notion of a god, a 'creator', was a notion formed in the childhood of our species, when individuals had no better explanation for the events around them, as our species world view has progressed, through scientific method, we have come to understand these phenomenon without the need to assert 'a supernatural god'. Sure, there are many things we do not understand, and most likely never will, but simply asserting a 'supernatural god' as explanation, not only explains precisely nothing, but is without ANY supporting evidence. Everyone, nowadays, is an atheist in relation to Zeus, Baal, Ra, Fairies, etc...however we do not require a word to describe this view, it is simply absurd, and the abrahamic religions are no different; perhaps a little more effective in their continuation of dogmas, however they will to soon vanish.
The way I see it, I see atheism to be the negative against the religious (of any faith) affirmative in an (eternal) debate. Note that I did not say that atheism is a religion - far from it. Both sides believe / contend that their point of view is the correct one.
But it is the norm for the affirmative side to justify it.
It's also the norm for the negative to refute the affirmative, as you say, but also put forward their contention and evidence to support it rather than statements that do not have any (easily found, to be honest) support.
You'll find that both sides of an argument will ask each other to back up their statements with proof, regardless of stance.
Atheists did not initially assert that God doesn't exist, they simply reject the assertion that he does.
Irrelevant. This is like the chicken or the egg.
Sorry you are wrong. If i assert that Elvis is alive, and someone asked "why do you think that'?" would it be okay for me to say "oh, You asserted Elvis does not exist, u know its a chiken and egg thing, it doesnt matter, believe that Elvis does not exist is just as superstitous, blah, blah" ? No it wouldn't be, however if we change place this in a religous context, your rational critique is bypassed by your indoctrinated bias; all those nights when daddy belted you with that bible.
I feel deeply embarrassed and sorry for those who hold a belief in supernatural daddies, mabye if you lived before the 18th century i could empathize, however its the 21st century...and its simply shameful.
