What Is Atheism?

Quick Answer

Atheism is the belief that there is no God or gods. People who are atheists do not follow a religion, but they still have their own ideas about right and wrong, and they can be just as kind and caring as anyone else. Atheism is not a religion itself; it is simply a different way of understanding the world.

Age 4

You know how some of your friends might go to church or temple or mosque because their family believes in God? Well, some families do not believe in God, and that is called atheism. People who think this way are called atheists.

Atheists do not think there is a God watching over the world. Instead, they believe the world works because of nature and science. They look at things like rain, stars, and animals and think those things happened on their own, without God making them.

Even though atheists do not believe in God, they still believe in being good! They think people should be kind, honest, and helpful, not because God tells them to, but because it is the right thing to do and it makes the world a better place.

You might have a friend whose family is atheist. That is totally okay! They are still good people who love their families. People can believe different things about God and still be wonderful friends to each other.

Ages 6-8 More Detail

Atheism means not believing that any god or gods exist. A person who is an atheist has looked at the world and decided that they do not think there is a God. This is different from being religious, where people believe God is real and important.

Atheists are not angry at God or trying to be difficult. They have simply come to a different conclusion about how the world works. Many atheists love science and think that nature, the laws of physics, and evolution explain how the universe and life came to be, without needing a creator.

One thing that is important to know is that atheists still have values and morals. They believe in being kind, telling the truth, and treating people fairly. They just believe these things because they think it is the right way to treat other humans, not because a holy book or God told them to.

You might wonder why your friend does not believe in God when your family does. That is because people come to different conclusions about big questions. Some people grow up in non-religious families. Others think about it for a long time and decide that God does not exist. Just like there are many religions, there are also many people who do not follow any religion at all.

Being atheist does not mean someone is against religion. Many atheists respect that religion is important to other people. They celebrate holidays like Christmas or Thanksgiving for the family time and traditions, even if they do not see them as religious events. The most important thing is that people treat each other well, no matter what they believe about God.

Ages 9-12 Full Explanation

Atheism is the position that no gods exist. The word comes from the Greek word "atheos," meaning "without gods." About 7 percent of the world's population identifies as atheist, and many more describe themselves as non-religious. Atheism is not a religion and has no holy book, no church, and no set of rules. It is simply a conclusion some people reach about whether God is real.

People become atheists for many different reasons. Some look at the evidence from science, such as the Big Bang theory and evolution, and feel these explain how the universe and life developed without needing a creator. Others struggle with the question of why a loving, all-powerful God would allow so much suffering in the world. Still others simply grew up in families where religion was not part of life, and they never felt the need to adopt one.

A common misunderstanding is that atheists have no morals or values. This is not true at all. Atheists build their sense of right and wrong from human experience, reason, and empathy. They believe in treating people fairly, being honest, and helping others, not because a higher power demands it, but because it leads to a better world for everyone. Many atheists are deeply involved in charity work, community service, and fighting for justice.

Atheism and religion do not have to be enemies. In many families and friend groups, believers and non-believers get along perfectly well. What matters most is mutual respect. An atheist can appreciate the beautiful music, art, and community that religions create. A religious person can respect that their atheist friend has thought carefully about these big questions and come to a different answer.

If you have a friend who is atheist and you are religious, or the other way around, the best approach is curiosity rather than arguing. Ask them what they believe and why. Share your own thoughts if they are interested. Some of the most interesting conversations happen between people who see the world differently. You do not have to change each other's minds. You just have to treat each other like the good people you both are.

It is also worth knowing about a related position called agnosticism. Agnostics say they do not know whether God exists and may feel the question cannot be fully answered. Some people describe themselves as "agnostic atheist," meaning they do not believe in God but also acknowledge they cannot be 100 percent certain. These are thoughtful positions, and the fact that people think so carefully about these questions shows how much the big questions of life matter to all of us.

Tips for Parents

Atheism can be a challenging topic to discuss with your child. Here are some practical tips to help guide the conversation:

D

DO: Follow your child's lead. Let them ask questions at their own pace rather than overwhelming them with information they haven't asked for yet. If they seem satisfied with a simple answer, that's okay — they'll come back with more questions when they're ready.

D

DO: Use honest, age-appropriate language. You don't need to share every detail, but avoid making up stories or deflecting. Kids can sense when you're being evasive, and honesty builds trust.

D

DO: Validate their feelings. Whatever emotion your child has in response to learning about atheism, acknowledge it. Say things like 'It makes sense that you'd feel that way' or 'That's a really good question.'

D

DON'T: Don't dismiss their curiosity. Responses like 'You're too young for that' or 'Don't worry about it' can make children feel like their questions are wrong or shameful. If you're not ready to answer, say 'That's an important question. Let me think about the best way to explain it, and we'll talk about it tonight.'

D

DO: Create an ongoing dialogue. One conversation usually isn't enough. Let your child know that they can always come back to you with more questions about atheism. This makes them more likely to come to you rather than seeking potentially unreliable sources.

Common Follow-Up Questions Kids Ask

After discussing atheism, your child might also ask:

Why doesn't my friend believe in God?

People arrive at their beliefs through many paths. Your friend may have grown up in a non-religious family, or they may have thought a lot about the world and decided that God does not make sense to them. It does not mean they are a bad person or that they have not thought about it. They have simply reached a different conclusion.

Are atheists against religion?

Most atheists are not against religion. They may not agree with religious beliefs, but many respect the positive things religion does for people, like building community and providing comfort. Some atheists do criticize certain religious practices, just as religious people sometimes disagree with each other. But being an atheist does not automatically mean being anti-religion.

Do atheists celebrate holidays like Christmas?

Many atheists do celebrate holidays like Christmas, Thanksgiving, and Easter, but they see them as cultural traditions rather than religious events. They enjoy the family gatherings, gift-giving, decorations, and special meals without connecting them to religious beliefs. Holidays can be meaningful for anyone, regardless of their views on God.

What is the difference between an atheist and an agnostic?

An atheist says, "I do not believe God exists." An agnostic says, "I do not know whether God exists." Some people are both, meaning they do not currently believe in God but admit they cannot be completely sure. Both positions are thoughtful ways of engaging with the big question of whether God is real.

Can an atheist and a religious person be friends?

Absolutely! Friendships are built on shared interests, kindness, and respect, not on having identical beliefs. Many of the best friendships include people who see the world differently. What matters is that both people respect each other's views and focus on what they have in common rather than what divides them.
