1. Disbelief in or denial of the existence of God or gods.
2. The doctrine that there is no God or gods.

Language origin: Greek

“a” (negative, negator) – “theos” (god) = “No God”


Theism – Belief in the existence of a god or gods, especially belief in a personal God as creator and ruler of the world. (


* “An atheist is someone who believes and/or knows there is no god.”
* “An atheist lacks belief in a god.”
* “An atheist exercises no faith in the concept of god at all.”
* “An atheist is someone who is free from religious oppression and bigotry.”
* “An atheist is someone who is a free-thinker, free from religion and its ideas.”


1. Lack of Evidence


The supporting evidence isn’t good enough for him to affirm God’s existence. (agnostic?)

2. Illogical


Says there is evidence contrary to God’s existence.

3. Non-Issue


Lack belief in God the way they lack belief in invisible space snails in orbit around Saturn.

Common Presuppositions

(NOTE – NOT universally adopted. The ONLY common belief is a belief that God does not exist.)

1. There is no God or devil.
2. There is no supernatural realm.
3. Miracles cannot occur.
4. There is no such thing as sin as a violation of God’s will.
5. Generally, the universe is materialistic and measurable.
6. Man is material.

7. Generally, evolution is considered a scientific fact.
8. Ethics and morals are relative

Example Argument

God is supposed to be all good and all powerful. Evil and suffering exist in the world. If God is all good he would not want evil and suffering to exist. If He is all powerful then He is able to remove all evil and suffering. Since evil and suffering exist, God is either not all good (which means he is not perfect and not God), or he is not all powerful (and limited in abilities and scope). Since either case shows God is not all good and powerful, then He does not exist.

Mission: Prove a negative, absolute statement
—————————————————— —————————————————————– —–

Your mission, should you choose to accept it – is to state that there is absolutely no god, and that the concept of god is absolutely false -then, to provethis statement: NO GOD =1

First, we have to make a couple definitions. A CANNOT be A and NOT A, at the same time.

To say there is NO God is an absolute statement. So, if you say that there is NO God, No God = NOT A. If you say that there IS a God, God = A. A cannot be A, and NOT A at the same time, remember. So, the mission is to prove that A =/= A – but A = NOT A.

If A = god, and NOT A = No god

A cannot be A, but MUST be NOT A, in order for NOT A to be true.

NOT A and A are not equal, and cannot have the same value – so, we must accept that NOT A =/= A.

In order for NOT A to be a true statement. A MUST be false. In order for NOT A to be accepted true, the axiom of “A =/= NOT A” MUST be accepted – thus, absolutes must be accepted, in order for there to be NO god. No is an ABSOLUTE statement – thus, A MUST be false, and it MUST be accompanied by a proof, for the statements GOD = A , and NO GOD = NOT A, to be logically true.

So, since we’ve established that “No God”, and “God” are mutually exclusive – we’ll move on.
———————————————————— —————————————————————-

“No God” is a negative value – so, the mission is to prove a negative. God cannot exist, and there must be proof of God’s non-existence – or there is still a possibility of A equaling A.
————————————————————- —————————————————————

To prove that A = A, however, is still pretty hard. It’s an axiom, like 0=0, or 1=1. To prove that God = A, requires that Not A also be proven false. So, on the other side, we’re also stuck.

But, we’ve proven that it’s impossible to “prove” God’s existence, or non-existence – and, we HAVE proven the existence of absolutes. So, it’s now possible to use absolutes in our argument,s henceforth. A, forever after, CANNOT also be NOT A – thus, unless you invalidate absolutes altogether, and thus, any scientific method, you’re stuck with absolutes as an axiom. So to accept that A cannot be NOT A did absolutely nothing but prove absolute exist. So, let’s move on.

———————————————————- —————————————————————– –

So, here’s the next question – if a statement is unprovable – how can it be absolute?

The answer?

It can’t.

So, the basic statement Atheism is founded upon is based upon belief, to put it bluntly – yet contains an absolute statement – which, in order to be undeniably correct, would have to prove a negative – something which has NEVER been done in the history of logical thought.

So, in order to back up that absolute statement saying there is NO god, you would have to prove a negative – but, how do you prove that the negative of something which you say does not exist, does NOT exist – without recognizing it’s existence?

On the other hand, any Religion has only the burden of evidence to bear – not the burden of proof – because all religions are based upon faith in the unprovable – not an absolute statement of fact. If you believe something, you believe IN something. You have no need to prove the non-existence of a thing – you just have to prove a thing exists. Also impossible, but not because of logical impossibility – but factual impossibilty. Noone, but the God believed in, can know ALL the facts – so, it’s unprovable. There is evidence, of course – which an Atheist can never have – there CAN be no evidence of the NON existence of something – because there would be nothing to see, if the thing which does not exist – doesn’t exist.

Existence is either believed, or disbelieved – but it is never known, with complete certainly.
