Here's how American Atheist describe their POV:
American Atheists -- Atheism
ATHEISM
Atheism is a doctrine that states that nothing exists but natural phenomena (matter), that thought is a property or function of matter, and that death irreversibly and totally terminates individual organic units. This definition means that there are no forces, phenomena, or entities which exist outside of or apart from physical nature, or which transcend nature, or are “super” natural, nor can there be. Humankind is on its own.
Ergo:
NOTHING exists (Nihilism)
However, the "...but natural phenomena (matter)" part starts one thinking that something DOES fill that void for an Atheist--and that is the god known as Empirical Evidence.
So, as an honest Atheist might say: "Nothing exists except that which we have faith is real which is empirical evidence--but we won't admit it requires a certain amount of faith and devotion to accept something as real (like those darned Theists are wont to do) because it would be a contradiction to admit we must reley on a sort of unprovable belief in the reality of any such empirical evidence to accept anything as true since NOTHING is objectively verifiable."
So you explain that atheists believe that there is nothing supernatural, and then you make the huge leap to "nothing exists." Where is the logical connection there? Matter exists, and nothing escapes causality.
Just because there is nothing supernatural doesn't mean nothing exists. You don't have to have faith in things that just are. Things are as they are regardless of your capacity to perceive them.
I am not arguing there is anything wrong with science or the scientific method--merely that there is a certain faith in "reality" that Atheism must accept as true to be able to even to understand or accept the world around them.
Faith in reality? I'm sorry but until the physical rules of nature shift on us I'm going to have to say that I have reason to believe in cause and effect, and it requires no faith.
This faith in the Scientific Method--or as I said, the god Empirical Evidence (EE)--makes the "practice" of Atheism--not exactly "A" (without) "thea" (god). They serve under the god EE in the religion of Science.
First of all, what evidence isn't empirical. Secondly, how does using evidence and reason automatically equate the scientific method to your new god? You seem to believe that everyone must have a god of some sort, be it a philosophy or a rock.
That is why I said there is no such thing as an Atheist (perhaps I should say "true" Atheist, or "absolute" Atheist), and that the specific philosophy can only be lived in an imperfect way--because it leads to nothing--and nothing in unlivable.
Does that even mean anything? Perhaps you aren't making a distinction between a strong atheist (There is no god) to a weak atheist (I don't have a reason to believe in your god.) The strong atheist's claim is just as fallacious as the mystic's because you cannot prove or disprove either way.
If the comment above my avatar doesn't explain my bias enough, I am a man who operates on zero faith. Sure I cannot know for certain the outcome of my actions and decisions, but I have reason for each of them, and though I may hope for a certain outcome, or trust in another, faith had nothing to do with the cause. I am an atheist, and I have been unimpressed with the best religion has to offer on deities.
I dare not claim there cannot be a prime mover, or infinite complexity to the universe, but a humanoid deity?
Things exist, and I cannot accept your claim that faith precedes science, or that science or atheism lead to nothingness.
