Atheism is not practiced anywhere. It is not a practice. It should not be viewed in religious terms. Atheism is the lack of, or the absence of belief in gods and that can happen anywhere in the world.
Think of it this way- not playing Golf is not a different sport. Following that example, atheism is a lack of religion and not a different religion.
Christain is leading. Atheism
Shinto religion is practiced in Japan.
If you mean where, as small scale place such as a church, nowhere. If you are asking on a larger scale, atheism is practiced around the world. In fact more and more countries are gaining atheists. The only country far behind on this bandwagon is the United States.
Christianity ofcousrse. Off late, Christianity is fast declining to Atheism, Buddhism, Islam & Hinduism.
Judaism is practiced all over the world. But the largest concentrations of Jews are in Israel and the United States (mostly in the New York metropolitan area).
Which area are you talking about. Christianity is all over the world in many tribes and nations.
The CCCP (USSR or Union of Soviet Social Republics) was always Irreligion, which is like Atheism, but not at the same time. Irreligion is the absence of religion. It was not practiced or anything. It was just not there. Religion was not a big role in the CCCP, so they did not bother with it.
We haven't lived in it yet. That's why our world is such a horrible place.
Yes, it is practiced all over the world.
Atheism is not a "unifying" force nor is it intended to be. Atheism is not a religion nor a political system and there is no central organizing entity. Since atheism is not driven by any strict set of doctrines and atheists have no motive to take control over other people, force people to become atheists or rule the world, atheism is a relatively benign personal choice to not accept a belief in the supernatural.
Shintoism, Christianity, Judaism, Islam, Hinduism and Buddhism. Shintoism is practiced in Japan, Christianity is practiced throughout the world, Judaism is practiced in Israel and Islam is practiced in the Middle East. Hinduism is practiced in India, and Buddhism is practiced in Southeast Asia as well as China.
Religion is a belief, conviction and practice of an individual or a social community in manifestation of a Creator for all existence in Nature, natural phenomenons or even as humans recorded in scriptures and practiced as rituals. Atheism is also a conviction in non existence of a supreme Creator for all existence.
