One who doesn't believe in god(s). Usually accepts scientifically demonstrated facts, and is generally willing to change one's mind should better evidence be presented.
As an atheist, I may not know completely how Life, the Universe and Everything came into existence, but I see no reason to subscribe to a belief in a magical entity to explain it.

To be without any religious beliefs.
I am an atheist. I don't believe in heaven, hell, spirits, or souls. I think of after-death as the same state as pre-birth. I have no creed, no rituals, no voices telling me to do crazy shit. Atheism is not a religion. Religious people like to call it one because their narrow minds can't imagine living without at least ONE delusion. If atheism was a religion then disbelief in Zeus would be a mythology, and clear would be a color.

someone who does not believe in any gods. there are two kinds of atheists: strong atheists believe that the existence of gods are impossible, weak atheists (called agnostics) don't believe in god, but would start believing in him if he were proven true.

atheists usually come in two flavors: atheists who don't believe in god based on science, evolution, the big bang, humanism, skepticism and logic. the second group, unfortunately, are goths and vampires who don't believe in god because it's "alternative" and "anti-establishment".

A person who does not believe in a deity
I don't believe in God, Yahweh, Allah (all the same deity), Vishnu, Shiva, Brahma, or any other god or goddess. Therefore, I am an atheist.

Someone who believes in science rather than a god or gods.

Note: This also excludes a belief in satan. Only satanists worship satan. Contrary to christian propaganda, atheists are happy, tolerant people and except in the cases of a religon being imposed upon them, they understand the diversity of beliefs, and conseal their distaste towards religon so as not to offend others.
1. Hey, you there, other atheist! Do you ever notice how we are so much happier than christians because we don't have to adhere to stupid, self contradictory rules, have Sunday morning to sleep-in, and have the knowlage that when we die, we loose all consious thought, and our bodies rot in a coffin.

2. Thankyou Mr. Atheist, without you, there'd be no TV, cars, computers, pornography or extra-warm socks because of how much christians hate science.

3. Wow, those christians sure seem angry at us atheists. Maybe its because our science has made their religon obsolete in filling the void of ignorance from thousands of years ago, and they are scared that they have based their whole lives around a fallacy, and that we are right and they are wrong.

Atheist-One who does not believe that God or gods exist. That's it. That's all there is to it. NEVER i mean fucking NEVER judge a whole group of people because of what some of them believe. Yes, some blindly condemn religion. Yes, some are just angry, angst-ridden teens. Yes, some say they don't believe but inside actually do. And yes, some are confused and don't know what to believe, or are just scared to. But some athiests actually CARE about the truth and have done research and personal reflection to come to a personal conclusion based on tons and tons of thought. Also, NEVER assume that you're right! No matter what you believe. Even if someone honestly believe something completely ridiculous to YOU, keep that to YOURSELF. Judging people BEFORE you really know them is parallel to racism, and people can NEVER be judged as a group. Some athiests are conceeded assholes who are so smug cause they believe they're right. But some athiests have considered the possiblities of higher powers and have actually TRIED to believe in greater enlightenment through God. I have my beliefs and that has NOTHING to do with my personality. I can have fun. I can use common sense and rationality. I think about consequences. I think about other people's feelings. I know that my reasons for this disbelief may offend you, so i KNOW that i have to keep them to myself unless asked to say why. People, you have YOUR beliefs of what you think is right. That doesn't mean you have to bring it upon other people, even if you THINK you're doing the right thing. Everyone has their reasons for thinking something, but someone's belief in their own personal TRUTH cant tell you who they are. Please, people respect each other. That's all the world needs. Respect and common sense.
Accept minor flaws, accept human imperfection, and accept people's identities. I'm not perfect. I KNOW there's a possibility that I'm wrong. Maybe some people just need to hear that.
Dude 1: Dude you coming to the party tonight?
Dude 2: Nah, sorry. Got church tomorrow.
1: Alright, man. Do whatcha gotta do.
2: Say you wanna come some time? Just so you can see what I beleive?
1: Sure, why not? I might be atheist, but who knows? Exploring the possibilities may find something that appeals to me more. It would be ignorant to just assume without personal thought that there is no higher power.
2: Glad to hear it.

(You see?! 2 people with completely different beliefs that can still be friends because they accept their PERSONALITIES over religion)
