The lack of belief in a deity or deities. Just that. Nothing else.

Atheism doesn't hold any answers to life's big questions. It won't tell you the meaning of life and it won't tell you how it all started. It's not a religion, not a philosophy, not a way of life. Atheism is quite simply *non-belief*.
#1: "I heard you're an atheist and don't believe in God, #2. If that's true then how did the universe begin?"
#2: "I don't know for sure. The leading scientific theory right now is the Big Bang theory, but that has a few problems and might not be correct."
#1: "If there's no God then where do we know right from wrong from?"
#2: "Again, I don't know for sure, but the general theory is that we evolved this feature because social creatures do better if unit cohesion isn't hindered by constant murdering."

Atheism isn't about answers. It's not really about anything, actually.

Absence of belief in god(s).
Atheism is absence of belief in god(s). It is not necessarily belief that no god(s) exist. Just as asexual is absence of sex in reproduction, not opposition to sex or asymmetrical is absence of symmetry, not opposition to symmetry. Atheism is simple absence of theism.

Frequently people confuse the theism vs atheism question with the gnostic vs agnostic question. The word gnostic means pertaining to knowledge. It is a question about whether a person is certain or "knows".

Everybody is either theist or atheist and everybody is either gnostic or agnostic. There are agnostic theists. They believe god(s) exist, but don't claim to know for sure personally. There are gnostic theists. They believe and claim to know for sure that god(s) exist. There are agnostic atheists. They do not believe in god(s), but do not claim to know with certainty that no god exists. There are also gnostic atheists who claim to know that no god exists. It possible and quite common among atheists to not have been convinced of the hypothesis that god(s) exist without taking the position that no god exists.

I can't believe Atheism doesn't make any prophets off of us.

The idea that there is no god. That's it.
Distance yourself from r/Atheism and the stereotype all atheists are whiny intolerant assholes who poke fun at innocent theists. Yes, there are some atheists that act like that, but the average atheist (think next door neighbour) is not like that.
Atheism is often associated with Nihilism. In some ways they are very similar, such as the rejection of religion. But there are other philosophical paths that do not involve religion, just as good as each other.
Atheism rejects the idea that there is an afterlife after we die.

There are two kinds of atheism: strong (positive) atheism and weak (negative) atheism. The difference between these two is basically that a weak atheist doesn't believe in God, while a strong atheist believes in no God.

Weak atheism is essentially the same as agnosticism. It states that since we have no proof of a God, we cannot know for sure that one exists. Strong atheism states that since we live in a scientific world where the existence of things is determined solely by their observability, we cannot assume anything unobservable to exist. God isn’t observable, therefore he doesn’t exist (cf. Occam’s Razor). This doesn't mean that an atheist wouldn't WANT to believe in God, it merely means that he has no REASON to believe in it/him.

Strong atheists often question the special treatment weak atheists – and theists – give to religion. If they believe that the tooth fairy or Santa Claus do not exist, why are they willing to give God a benefit of the doubt?

Strong atheism is often equated with religion since it takes a strong stance on the issue. This is, however, fallacious. Religion is not based on rationality, and strong atheists value rationality over fantasy. Therefore atheism is not parallel with religion.
I do not follow atheism. I merely concur with it.

Atheism is the disbelief of the existence of a god or gods in any religion. Often confused with Satanism by bigoted Christians.
Atheism: Prove God exists.

Christianity: Prove he doesn't!

Atheism: Prove the Flying Spaghetti Monster doesn't.

Christianity: ...

Atheism: That's what I thought.

A rejection of the belief in the existence of a God or Gods. Atheism itself is not a religion or a belief, but is accepted within some religious and spiritual belief systems, including Jainism, Buddhism, Hinduism, Neo-pagan and Wicca. Although some atheists are also anti-theists, who oppose organized religion others are merely indifferent. In spite of some people generalizing atheists as being immoral, they tend to have a lower crime rate and as a population are no less moral than theists.
Scientists and highly rational people tend to subscribe to atheism because they believe in Occam's Razor:
"A principle urging one to select among competing hypotheses that which makes the fewest assumptions and thereby offers the simplest explanation of the effect".
