We Are Atheists Because...

There is no proof of the existence of god.
There is no need of, or use for, a god.
A good god would be useless if were not powerful. A powerful god would not deserve worship if he were not good. There is no all powerful good god; otherwise there would be no imperfection.
If this is the best world god can make, the stories of Heaven must be lies.
History shows that godism is accompanied by ignorance and superstition. There has never been such intolerance and persecution as godists have practiced.
Godism had to be fought when humankind made its successive steps toward science, liberty, and reform. Godism was invented in the earliest days of mankind's ignorance. It is incredible that primitive humans guessed wrongly about everything else, but discovered the truth about the origin of life. Everything about which science has discovered the origin was claimed previously to have been the work of a god.
Godism recedes when a new fact is discovered. No new discovery ever supports a theistic explanation of anything. All revelation proves, on investigation, to be human, and generally fraudulent.
Godism is consistent with crime, cruelty, envy, hatred, malice, and uncharitableness.

Atheism Teaches That...

There is no heavenly father.
Humankind must protect the orphans and foundlings, or they will not be protected.
There is no god to answer prayer. Man must hear and help man.
There is no hell.
We have no vindictive god or devil to fear or imitate.
There is no atonement or salvation by faith. We must face the consequences of our acts.
There is no beneficent or malevolent intent in nature. Life is a struggle against preventable and upreventable evils.
The cooperation of humankind is the only hope of the world. There is no chance after death to "do our bit." We must do it now or never.
There is no divine guardian of truth, goodness, beauty, and liberty. These are attributes of humankind. We must defend them or they will perish from the earth.
