There are number of beliefs that are common among proponents of Western World atheism which will shortly be covered. Also, an examination of the subject of atheism and beliefs quickly leads to the reasonable conclusion that the beliefs held in "faith" by atheists are without any supporting evidence.
Atheism and beliefs about the origins of the universe
- Big Bang theory: atheists believe that the universe was created by the big bang approximately 13 billion years ago, with no plausible cause or catalyst.
Atheism and beliefs about the origins of life
- Abiogenesis: atheists assert that cellular life was materialistically generated from inorganic material, the "primordial soup." Abiogenesis has not been established in any scientific study, and is profoundly unlikely, given the miniscule odds of the right mix of chemical and environment existing, which are necessary for organic life.
- Materialistic Evolution: atheists believe that all life on earth developed from the first organic cells, according to Darwin's Theory of Evolution. Importantly, they categorically reject the potential of God's hand in this process, though without cause (see: Theistic evolution for a different take). See The Theory of Evolution for the inherent problems of this belief.
- Socialism: While there are certainly atheist capitalists, many atheists in history have tended towards socialism and communism and modern communism was explicitly atheistic in origin. Many atheists believe laissez-faire capitalism is unproductive, even though capitalism has provided the greatest growth of productivity and standards of living in human history.
- Limited freedoms: atheists believe that individuals should have free speech, so long as it does not contradict atheistic or evolutionary doctrine.
Atheism and beliefs about history
- Science and Christianity: atheists believe that religion is antithetical to scientific research and deny that Christianity was important to the development of science, when in fact the Scientific Revolution was brought about by scientists seeking a greater knowledge of God. 
- Democracy and Christianity: atheists believe that democracy does not rely on Christianity, even though they are clearly linked in Western history and no atheist democracy has ever succeeded.
- Atheists deny that many of the Founding Fathers were Christian, pretending instead that they were Deists.
- Naturalism: atheists believe that the universe only operates through natural processes, and is limited to what can be observed. Most scientists, (from Newton to Einstein to present) on the other hand, assert that while the observable universe follows natural processes, first causes are unknowable, and our knowledge is limited to what we can detect, leaving open the potential for the spiritual, the soul, and divine acts of God.
- Scientism: atheists believe that all knowledge and aspects of life can be refined to a science (see Comte and positivism), including religious belief, ethics, morality, and the soul.
- Human improvement: atheists believe that humans have grown increasingly moral and intelligent as time has gone on, and that people can be improved or perfected through education and liberal institution-crafting, without relying upon God to cleanse sin.
- Unbounded reason: atheists believe that human reason is capable of comprehending absolutely anything, a theory long since rejected by moral philosophers such as Kant.
Religion and God
- Comprehensible God: extending from an arrogance in their own reason, atheists believe that if God exists, He and His works must be comprehensible. Therefore, they argue that God does not exist from paradoxes and such arguments as the Problem of Evil, which God transcends.
- Disbelief from silence: atheists believe that God does not exist, merely because there is no absolute proof that he does exist, a logical fallacy. Atheists believe that science disproves God but have no actual evidence that this is the case.
- Moral superiority: atheists believe that religion causes strife and that atheists are inherently morally superior to theists. This flies in the face of actual evidence, which shows that atheists are markedly less generous than theists.
- Moral relativism: atheists believe that no absolute morals exist, God-inspired or otherwise, and thus rely on vague, transient, and corrupting notions of morality.
- Satan: Atheists deny the existence of Satan, while simultaneously doing his work.
- Superior intellect: atheists believe that atheists are inherently more intelligent than theists, and some even consider this an "inevitable product of ongoing social selection."
