Atheism is the absence of belief in any Gods or spiritual beings. The word Atheism comes from a, meaning without, and theism meaning belief in god or gods.
Atheists don't use God to explain the existence of the universe.
Atheists say that human beings can devise suitable moral codes to live by without the aid of Gods or scriptures.
They once had a religion and have lost faith in it.
They live in a non-religious culture.
Religion doesn't interest them.
Religion doesn't seem relevant to their lives.
Religions seem to have done a lot of harm in the world.
The world is such a bad place that there can't be a God.
It is possible to be both atheist and religious. Virtually all Buddhists manage it, as do adherents of other religions,such as Judaism and Christianity.
But many atheists are also secularist, and are hostile to any special treatment given to organized religion.
♦ATHEISTS AND MORALITY
Atheists are as moral (or immoral) as religious people.
In practical terms atheists often follow the same moral code as religious people, but they arrive at the decision of what is good or bad without any help from the idea of God.
