What do atheists believe?

Modern atheists hold many beliefs that are common to all or nearly all atheistic believers. To be sure, there are variations based on ongoing advancements in science and mathematics. But such differences are not pivotal to the modern atheist’s beliefs. We, being all modern day atheists, do verily believe and endorse the following tenets of Atheism and acknowledge them to be true and proven, by reasonable standards of logic, reason, science, mathematics, and/or observation:



Based upon the conclusions of those we reasonably believe to be the most intelligent, learned, rational, and knowledgeable in relevant intellectual pursuits, we believe that the theory known as The Big Bang correctly describes the beginning of our universe. We believe this is the only acceptable logic behind the creation of this universe.



Based upon the conclusions made by learned men we believe:

1) That life came into being without purpose and without intelligent design or intervention.

2) That humans have not yet been able to create a living organism from inanimate materials, but one day we will be able to do so.

3) That some characteristics of things that are “alive” are that they: undergo metabolism, have a capacity to grow in size, maintain homeostasis, respond to stimuli, adapt to their environment and reproduce.

4) That concurrently with the advent of Life, The Speck revealed an additional law of nature – evolution. According to the law of evolution, living organisms evolve and adapt to the circumstances of their existence.

5) That the advent of living creatures also brought with it the concept of “purpose” to the universe. Living creatures imposed their own purposes on the universe. Two primary purposes which life imposed for itself are survival and reproduction.

6) That there is no identifiable reason why living things began to impose purposes into their existence, and we will never understand why this happened because life was created without purpose.

7) That more complex living organisms are more active in imposing their purposes, often affecting the purposes of other living organisms. The effects on competing organisms tend to be negative for one or all organisms competing for survival and reproduction. Cooperative organisms tend to enhance one another’s purposes through a relationship we refer to as symbiosis.

8) That from their meager origins as single cell organisms approximately 3.8 billion years ago, living organisms on earth, through applying their inexplicable purposes, evolved into the more than 8.7 billion separate species existing on earth today.



Regarding human beings, we believe:

1) That humans (homo sapiens) evolved according to the inexplicable purposes of their ancestor species, ultimately becoming the most evolved and intelligent life form on Earth.

2) The human brain controls all thoughts, emotions, speech, and actions of humans.

3) That the human brain is made up of two kinds of cells: neurons and glial cells. The entirety of brain activity is controlled by the interaction of its cells with electrical impulses (usually generated elsewhere in the human nervous system), and chemicals called neurotransmitters which exist in spaces between the brain cells (collectively, human electrochemical brain activity).

4) That human electrochemical brain activity gives humans free will and the ability to make choices regarding the individual human’s actions and inactions.

5) That such choices in turn affect human electrochemical brain activity to cause the human electrochemical brain activity to make additional choices.

6) That the human’s never-ending chain of choices, as determined by human electrochemical brain activity, become the human’s character or personality.

7) That the individual human’s personality or character, and his interactions with other living and inanimate objects determine: a) how the individual human will act or fail to act; b) what the individual will believe or not believe to be true; c) whether the human will choose purposes for his existence and which purposes he will choose.

8) That outside the realm of human electrochemical brain activity, there is no good or evil, right or wrong, fact or fallacy, love or hate, intelligence or idiocy, reason or insanity.



Occam’s razor holds that, when selecting among competing hypotheses we should usually select the one which offers the simplest explanation, the foregoing beliefs are the simplest explanation for human condition. It logically follows that there is no god and we reject the possibility that god exists.

Some questions on atheist beliefs answered

How does one become an atheist? Some people are born that way and never buy into religion to begin with. Others grow up with religion and begin to question it later on. It usually happens in college, or during a midlife crisis, or after a traumatic experience that doesn’t quite fit in with the idea of an all-loving God.

Although it’s theoretically possible for a believer to become an atheist just by analyzing his beliefs in a logical and detached manner, such cases are rather rare. After all, religion is a very sensitive topic for most believers – it’s one of the first things they’ve ever learned, part of the foundation of their entire identity. Try challenging somebody’s beliefs and you’ll often get the same angry reaction you’d get if you insulted that person’s mother.

If you don’t believe in God, what’s the meaning of life? The meaning of life is to find a meaning. It’s what you make of it. For some people, it could be the pursuit of money, for others it’s serving their country or being a good parent. We atheists come from all walks of life, and we’re all different, except for our lack of belief in gods. Since we are not an organized movement or a religion, there is no official atheistic position on the meaning of life, just as there is no atheistic consensus on the best kind of ice cream.

Atheist beliefs just make a person selfish!

Some of us are selfish, and some of us are not. Sure, we get to sleep in on Sunday mornings, but just because we don’t want to spend our time praying to an invisible man in the sky, doesn’t mean there’s something inherently wrong with us. And moreover, what is more selfish: following a moral code and taking responsibility of all your actions, or justifying your wrong deeds just to score enough brownie points in the eyes of God?

  1. The most non logic think I ever see is life came without purpose, ok where live will go after die and who controls the time to die on the other who coordinates when life dies from legs,abdominal to head.

  2. I found this to be a well thought out explanation of your belief system. As a Chaplain I explore all belief systems in order to support people as they journey toward death. This was helpful.

  3. ‘Nobel Prize winner Ernest Hemingway is seen as one of the great American 20th century novelists, and is known for works like A Farewell to Arms and The Old Man and the Sea. … Born on July 21, 1899, in Cicero (now in Oak Park), Illinois.’

    Yes, he won a prize for writing his stories – but no recognition for the one who wrote the great book of existance – that wrote itself over billions of years after an explosion from material that didn’t exist , in a universe that didn’t exist . Was that a thought I just had ? No it can’t have been.

    1. P. Tiemens I enjoyed your response. It had a good lead in and followed up with a touch of philosophy.

      Essentially you stated that every story has a writer, therefore God exists. I don’t mean to come across as crass, you obviously have good taste in reading material, but let’s ponder on the God of the gaps. Certainly, there’s more behind the Big Bang than Hemingway, nothing, or even God. Think on the continual pull of gravity; it caused the gases to collapse in on themselves and explode; why wouldn’t all of that matter that exploded turn in on itself once again? Just a theory, but a theory that attempts to explain a cycle of cause and effect. Following the creator theory we’d end up with either the spontaneous creation of a complex being or an infinite creation of creators. Much like the theory of evolution, simpler is better. Gravity, to me, is much simpler, therefore better.

      Personally, I’m navigating my way through Herman Melville’s book, Moby Dick. It’s heavy on the religious undertones, but doesn’t shy away from describing the intimacy between “strange bedfellows”. It’s worth a couple of glances if you view atheists as savages, or Queequegs, as the book depicts.
